Added A_ClearOverlays(int start, int stop, bool safety).

Browse source 
- Clears a set of overlays in ranges [start,stop]. If unspecified, wipes all non-hardcoded layers. Safety determines whether to affect core layers or not (i.e. weapon). Returns the number of layers cleared.

Added no override boolean to A_Overlay and a boolean return type.

- If true, and a layer already has an active layer, the function returns false. Otherwise, sets the layer and returns true.
