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.

Talent listing

Also added different sorting methods

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.

Randart randboss updates

Fixed several bugs with randart and randboss generation.
Randbosses will not be created with duplicate or incompatible classes.
The Last Hope merchant should no longer create inappropriate randarts for the player.
NPCs with spells should no longer be spawned with inappropriate equipment (no more arcane disruption).
Added support for more random Fixed artifacts.
Not all antimagic actors are Zigur followers.

generateRandart parameters work correctly, and new parameters have been added.
game.state:addRandartProperties(o, data) function added to allow random properties to objects.
new resolver to calculate NPC ai_tactic based on talents known. (still in development)
