Performed a fairly major overhaul of mdl2spr, the Quake model conversion tool.  Details are as follows: - Combined the programs mdl2spr (for MDL models) and md22spr (for MD2   models) into a single application. - No longer requires an external "palette.lmp" resource for extracting   skins from MDL files, thus simplifying usage. - Cleaned up and organized the project.  Cleaned up the code considerably   (though it can still use more cleaning).  Folded out redundant code. - Skins extracted from Quake 1 MDL files are now written as PNG files   rather than PCX files, and are thus immediately usable by CS (unlike PCX   images which CS can not deal with).  Eliminated the old PCX code. - Added a CS makefile so that it can be built easily on all platforms   which are supported by CS. - Improved the documentation and moved it to the standard 'docs' directory.
