Rewrite PVP Talent Load/Trigger to use SpellIds

Instead of indexes. This breaks all existing pvp talent trigger/load
options, though a lot would break anyway with the class changes of TWW.

This ensures that in the future patch changes should be less likely
break the load/trigger options. And improves cross-spec setups.

Fixes; #4557
