Merge branch 'callbackOnAITalentTactics' into 'master'

Add a new hook/callback, ActorAI:aiTalentTactics/callbackOnAITalentTactics

This hook/callback allows modifying talent tactical table. It is useful for sustains that modify other talents' behavior, like Arcane Combat, and allows more fine-grained AI management.
This modification may significantly buff Arcane Blade npcs.
