Update power use descriptions for zone specific world-artifacts, boss, quest, and special artifacts.

Updated handling of weapon special effects to pass the special effect field to the object code (facilitates handling multiple effects within object definitions).

Blighted Maul's on hit shockwave will not hit the primary target.

Wintertide's winter storm effect will expand in size to match its effect.
Updated the icestorm particles effect to accept radius and density parameters (this might benefit from some more tweaking).

Reduced the number of mental effects the Wintertide Phial will remove.

The Crystal Focus can now be applied to shields (updates the special_combat fields appropriately).

Prox's Lucky Halfling Foot benefits from Charm Mastery.

Penitence cures a more reasonable (few) number of diseases.

Updated the DAMAGE_SHIELD definition to note damage reflection in its tooltip and show shield strength in it's icon.

Awakened Staff of Absorption gets a special damage message and death message for the player if he manages to kill himself with it.

Changed Umbraphage's damage calculation to actually care about it's charge level (slight nerf).
Fixed a bug with Butcher that could cause its rampage not to activate on damage.  Now benefits from Charm Mastery.
Stormlash's AOE effect is correctly centered on the target, rather than the user.

DamageType.LITE now reduces the unlit value of grids with darkness if can't remove them. (Fixes a possible abusable bug with Umbraphage.)
Updated the tooltip for the Invisibility effect.

Updates the power descriptions of charm powered boots, cloaks, light-armor, mindstars, and staves to be more descriptive.

Minor bugfix to Object:getUseDesc to reference the correct actor

Updated resolvers.charm to allow specifying additional .use_power fields.

Adds rounding to Augmentation. Clarifies the psionic combat modifier. Corrects the way the psionic combat modifier is handled in combat.lua (and hence the weapon tooltips). Buffs the base mindstars slightly and slightly nerfs artifact mindstars to reduce the huge gap. Adds an icon for Psionic Maelstrom, though Nagyhal says he can make it better.

Object usable power descriptions can take the user's stats into account to provide more information on their effects.
Updated on use descriptions of charms and several artifacts.
The talent cooldown for on use powers can be any talent (not limited to T_GLOBAL_CD as for charms).

gave saner power scaling to acid wave rune and sun infusion so high level characters may possibly save against it
