-Cleaned up the talent system specific classes.
-The ResourceManager now loads talents aswell.
-Cleaned up, and made the EntityResource system scriptable.
-Fixed the stat signals, the stat parameter was null every time. ("this" should've been wrapped in a Ref.)
-Removed the old, now unneeded SpellCastData stuff from Entity.
-Small interface fixed to stat, also fixed applying and deapplying modifiers.
-Fixed AuraStatAttribute's bindings.
-Made the aura commands a little more intuitive.
-Added gcd callback bindings.
-Has Global Cooldonw in spell is now defaults to true.
-Small binding fixes.
-is_debuff is now just debuff.
-I realized that Godot Vectors, and Maps are made in a way, so that they don't need to be dynamically allocated. So none of the vectors, and maps are pointers anymore in Entity.
-PlayerTalent is a Reference now.
