Partially (but mainly) resolved Mantis #753 by making monsters, NPC, and Floor Items visible even covered.

Next Step would be to add a caching system for multi-layered sprites + copy functions for SDL and OpenGL.
Then, I'll be able to finish this, by making also players visible when covered...

But Kage asked me (each and every hour) to do something else first ;)
