Small fixes

annoying annoying backspace bug

Debug function help fix

* Fixes a long-standing, slightly annoying command-line bug in the lua console.

Merge branch 'LootRebalance' of http://git.net-core.org/housepet/t-engine4 into housepet/t-engine4-LootRebalance

Conflicts:
	game/modules/tome/data/zones/scintillating-caves/zone.lua

Additional npc objects

* Updated remaining World Artifacts, Quest Artifacts, and Special Artifacts to use the new interface.

Object use tactical tables can be an explicit function in the object definition.  This makes complex AI tactical tables simpler to code and more efficient to run.

Objects that have an instant talent as their activatable ability use no energy by default.
Moved after object use checks for breakStepUp, breakStealth, breakLightningSpeed, breakReloading, and breakSpacetimeTuning from mod.Player to mod.Object.

Artifact changes:

Terrasca (which works the same) uses a new "absolute" resistance that is updated as needed by callbacks.

Added new callbacks: callbackOnTemporaryEffectRemove and callbackOnTemporaryEffectAdd to supplement callbackOnTemporaryEffect

Buffed Exiler to have a chance to affect non-summons.

Modified Spellhunt remnants: They gain a maximum of 1 material level per artifact crushed, but can spawn at any level in the game (adjusting their material level to the zone).  Made more rare to compensate.

Cuirass of the Dark Lord slightly buffed bleed damage based on Physical Power and has advanced ai.

Awakened staff of absorption, slightly buffed to bypass most defenses.

NPCs:

Will try to equip their drops if possible (cannot replace default equipment unless the replacement is the same type and is more unique).

Updated GameState:checkPowers with an "antimagic_only" mode that is used for test actor-equipment compatibility.

Updated some boss definitions to be able to equip their unique drops and adjusted talents to compensate for the abilities of the equipment they can use.

Added the Staff Mastery talent to many casters (including bosses) that primarily equip staves.
Command Staff talent available to NPCs, which will now spawn with the most appropriate aspect selected.  (THIS IS A SIGNIFICANT BUFF TO MANY STAFF WIELDERS.)

Updated fixed artifact staves to use the new flavor system.

AI:

Updated the tactical tables for a number of talents (mostly that were used by various activatable items).

Updated tactical and talented AI's to allow NPC's to act again immediately after using an instant talent and added safety code in talented and tactical ai in case of failed talent use.

flee_dmap_keep_los AI will allow the ai to run farther if it has sufficient moves.

The tactical AI writes the selected tactic to the ai_state table as a parameter for talent.action functions.  This fixes a bug where NPCs that were activating tageted abilities to flee were moving closer to their target instead.  So an NPC using phase door, for example, will try to teleport closer when the "closein" tactic is active and further from its target when the "escape" tactic is active.

The tactical AI will take the duration of detrimental effects into consideration when evaluating cures.  Fixed a bug in tactical ai that was causing mistargeting of combination damage and heal/cure talents.

Updated the Rush talent to allow targeting unoccupied spots -- to allow the ai to use it to close when out of range.

Bugfix stealth&sleep inventory

* Fixes bugs with sleeping characters being able to change equipment (put on a lucid dreamer robe, for example), drop and pickup objects.
Fixes bug allowing stealth to be used with heavy armor (by changing gear while it is active).
Enhanced stealth info.

NPC Object Use

This change allows NPCs to use activatable objects.  This is a fairly large commit with some (minor) engine changes.

Basically, when a usable object is added to an Actor inventory (and can be activated -- generally worn in the appropriate slot, .no_inventory_access not true), the Actor may get a (hidden) talent that can be activated to use the power.

These are a new class of talents (.is_object_use) with a new flag (.never_fail) that prevents them from being interfered with by most actor effects.  They are available to the player via the UseTalent dialog in a new section, and the usual automatic use, confirmation and ai_tactical weights are supported. (The parameters follow the object if they are moved within the party, as appropriate.)

Objects that use a talent for their power generally don't need any changes, but use_power and use_simple generally must include extra data/functions (range, radius, target, tactical) with the power definition for the ai to use them properly, similar to the structure for talent definitions.  Generic powers with no tactical info will generally not be used by the tactical ai due to low weights, while dumb ai types may use them randomly.

(See the header section of mod.class.interface.ActorObjectUse.)

In summary:

Objects with a .use_power field are usable unless .no_npc_use (which may be a function(obj, who)) is true.

For these items:

         use_power = {
		name = constant or function(object, who), description of the power for the user

		power = number, power points used when activated

		use = function(object, who), called when the object is used, should include all effects and special log messages

		target = table or function(object, who), targeting parameters (interpreted by engine.Target:getType and used by the AI when targeting the power)

		requires_target<optional> = boolean or function(object, who), if true, the ai will not use the power if it's target is out of range, should generally be false for powers that target the user

		tactical = {TACTIC1 = constant or function(who, t, aitarget),
				TACTIC2 = constant or function(who, t, aitarget), ...} tactics table for interpretation by by the tactical AI (mod.ai.tactical.lua), uses the same format as talents, t is the talent defined here

		range<optional> = number or function(object, who), should be defined here to allow the AI to determine the range of the power for targeting other Actors with the power, defaults to 1

		radius<optional> = number or function(object, who), as range, defaults to 0

		on_pre_use<optional> = function(object, who), optional function (similar to talent.on_pre_use, to test if the power is usable via the talents defined here (return true to allow use)

		on_pre_use_ai<optional> = function(object, who), like on_pre_use, but only called by the AI, generally used to make the ai smarter by telling it when not to use the power

	}

	The raw talent level of the activation talent(defined here) equals the material level of the object.

Objects with a .use_simple field (uniquely defined, mostly for consumables), are not usable unless .allow_npc_use (which can be a function(object, who) is true or the .tactical field is defined.
They otherwise use the same format as .use_power.

Objects with a .use_talent field use a defined talent as their power.  They are usable if .allow_npc_use (which can be a function(object, who)) is true or talent.no_npc_use is not true and use_talent.no_npc_use (may be a function(object, who)) is not true.

For these items:

	use_talent = {

		id = string, talent_id to use (i.e. Talents.T_ILLUMINATE)

		level = number, raw talent level for the power (uses the user's mastery levels)

		power = number, power points used when activated

		on_pre_use<optional> = function(who, t), override talent.on_pre_use function, t matches talent_id

		on_pre_use_ai<optional> = function(who, t), override talent.on_pre_use_ai function, t matches talent_id

		message<optional> = function(who, t), override talent use message if any, t matches talent_id

	}
	The raw talent level of the activation talent equals the talent level specified in use_talent.

This commit updates charms(amulet, belt, boots, cloak, light-armor, mindstars, ranged, staves, torques, totems, wands, weapons), some fixed arts and most of the boss artifacts with the required fields to use the items.  This includes fixing the ai tactical tables for several related talents. Randombosses and several types of NPC's (with tactical AI) get a usable charm (in the tool slot).

Most of the general fixed-arts (those without use_talent) still need to be updated.

Roguelike mode characters can now enter the Eidolon plane by a special exploratory farportal event, thus making Utterly Destroyed achievement possible even in Roguelike mode

New string.prefix and string.suffix functions

Deus Ex Machina achievement altered and now possible to get
