Title: Core/Spells: Misc fixes.

* Bryntroll's Drain Life should not crit.
* Bestial Wrath can be used while under CC since patch 3.3.2

Patch 3.2.2 (2009-09-22): "Bestial Wrath and The Beast Within Changed to function like PvP Trinkets, removing any movement impairing effects, and giving immunity to these effects for 10 seconds.", also the tooltip doesn't say this, but it now breaks all forms of CC that a PvP trinket would break (including Cyclone,Sap, etc.).

As for relating to Bryntroll, the Bone Arbiter:
