More masteries

Allows more flexible weapon masteries.

Training Talents can have the following fields:
- getMasteryPriority(self, t, kind) - Only the talent with the highest is used. Defaults to the talent level.
- getDamage(self, t, kind) - Extra physical power granted. Defaults to level * 10.
- getPercentInc(self, t, kind) - Percentage increase to damage overall. Defaults to sqrt(level / 5) / 2.

As a side effect, stuff like lethality now shows up in weapon tooltips.

Training Talents can have the following fields:
- getMasteryPriority(self, t, kind) - Only the talent with the highest is used. Defaults to the talent level.
- getDamage(self, t, kind) - Extra physical power granted. Defaults to level * 10.
- getPercentInc(self, t, kind) - Percentage increase to damage overall. Defaults to sqrt(level / 5) / 2.

Should be compatible with all existing masteries.

fix bug in pickupFloor

Adds support for inventory-specific stack_limit parameter when defining an inventory. (in .infos or actor.body table.
This affects addObject, removeObject, sortInven, wearObject, pickupFloor, dropFloor,
Improves object stacking functions to handle a specified number to unstack/stack.

Fixed a bug when inspecting actor inventories in debug mode.
Fixed a shore bug when buying stacks of objects.

updated mod.Actor.doWear doTakeoff and doDrop functions
Player can drop partial stacks.
Updated party transfer dialog.

Spellcraft fix

Makes spellcraft:
Only work on spells.
Actually use the spellpower bonus it says it does.

Allow negative powers

Allows negative combat_spellpower and family to bring you below your basic stat level for powers.
Needed because currently EFF_INTIMIDATED does nothing the majority of the time, since most enemies don't have anything boosting powers above the stat level.

Add shield speed

Adds a 'shield' speed type, so 'quick' weapons will no longer make shield pummel faster.
Also makes room for a possible quick-acting shield ego/artifact.

Speed fix for edge

Edge was having trouble merging some PM talents in.
