Add support for floor item sprites

This commit adds a sprite hierarchy (Sprite->ImageSprite,AnimatedSprite,CompundSprite;
CompoundSprite,Actor->ActorSprite;ActorSprite->Being,FloorItem) to collect common
functionailty into new base classes which will make other Mantis tickets easier to do.
Also allows monsters to use particle effects.
