* refactor to use onleave and onenter instead of spell_area

allows players to right click remove adal's buff

* add MapMgr.h

* refactor: use condition enum instead of uint32, prefix WORLD_STATE where needed

* remove lock from WorldState::Update

sWorldState->Update() is only called from World::Update

* remove unsafe SmartAI action of setWorldState
