Fixes compatibility issues between Deathknight and other addons.
(This is only a patch, it requires the original Deathknight addon to work : https://te4.org/games/addons/tome/deathknight)

Fixed conflict with Frost Invoker's frost tree. (https://te4.org/games/addons/tome/frost_invoker)
Fixed various talent names conflicts with Dread Necromancer (https://te4.org/games/addons/tome/dreadnecromancer)

Sneaks in after Necromancy+, Eternal Darkness and Deathknight are done and makes all their stuff coexist. Probably makes Necromancers OP.

Adds the Deathknight class. See forum thread for details.
