Added SpriteAngle and SpriteRotation properties.

Browse source 
- Includes four functions, A_SetSprite(Angle/Rotation) and GetSprite(Angle/Rotation).
- SpriteRotation offsets the angle of the sprite, allowing for actors to move backwards or sideways for example.
- SpriteAngle requires +SPRITEANGLE and sets the actor's sprite to the absolute rotation found at that angle. Overrides SpriteRotation once the flag is on.
