RLTiles complete code rewrite: now much more robust and functional.

Added PNG and non-palettized image input.  Added PNG output.  Added better tile
packing and support for tiles of different sizes. Converted all BMPs to PNGs
(for space and explicit transparency reasons.) Added the 48x32 pandemonium
demon tiles, but these are not yet used in game.  Added Bill B.'s portal tile
(finally).

The Win32 makefiles are not updated quite yet and thus will not build.  Sorry.
