Added RelaxationTechnique and CognitivSkill enums to Player to allow setting the current skill or technique.
Added proper enums and replaced use of strings for CognitivSkill Enums. Refactored EventFactory's FireCogntivSkill event to be thread-safe when used with EmotivHandler. Added a Brain script which will eventually replace the managers and mana prefab and allow creation of them both once and allow them to be carried over to other scenes.
