Added a Unit parameter to BuffManager so it knows which unit to apply new buffs to. NOTE: It's important this isn't stored as it's unit property since causes it to be unset when lower priority unique buffs are set inactive.
Fixed a lower case enum.
Propagated the setEnabled method call to the Value since it is not a child and does not happen automatically.
Modified StatTotalScaled to accept a reducing scale stat in addition to the increasing scale stat. For use by Attack Speed. Movement Speed needs a much more complex combination of stats.
Added an ATTACK_SPEED_REDUCTION stat type. Removed the ATTACK_DAMAGE_PCT stat type since it is not used.

Added a comment to SotD passive to clarify a negative ATTACK_SPEED stat mod.
Added the Cold Steel named effect. Currently only added for Warden's Mail.
