December updates

New month, new update thread.
- The graphic engine has been optimized quite a bit today, the sorting of sprites is now more efficient and done only when neccessary.
- The isometric engine is now fully fonctionnal.
- New sprite options: SO_BACKGROUND, SO_TOPMOST (for z ordering) and SO_ISOTILE. The SO_ISOTILE will tile the sprite in an isometric way.
- New ISODEMO.PPL demo.
This release should be out by the end of the week (Friday probably).
