Subject: - fixed typos in csprite's code generator for nasm
X-Git-Url: http://git.mutantstargoat.com/user/nuclear/?p=dosdemo;a=commitdiff_plain;h=4b1cef5f03023a4977c1a0dd0e7464fd4cc1044c

- fixed typos in csprite's code generator for nasm
- integrated (in the UNIX build only) automatic generation of compiled
  sprites with csprite
- converted the UNIX build to 32bit, to allow using the same assembly
  code as with the DOS version (again for compiled sprites mostly)
