Adding new class animations
===========================
Player.txt contains animation names the player has to have loaded.
<className>.cpp contains walk and idle animation references that must be loaded in the Initialize() function.
Animation.cpp contains the SetupClassWalkIdleAnimations() function which all classes need to implement with their spritesheet and class name (all caps) to create the WALK and IDLE animations in the animation database.
	All other custom player class animations must be added here too.
