MakeProgramZip is now MakeZip

- It can be used to turn any directory of files into a zip. We also now use it
  to generates a games zip which has the game-specific code modules in it.
- Moved Doom2 and DoomRLSM into the games zip.
Added a mouse cursor resorce for use later.
Various code changes, begin revising the video code

- The video screen is now its' own class.
- We no longer compile under WIN32 since Python demands it have an stderr.
- Tell Python where we expect the exact program zip to be.
- Pass Python the -I parameter to enable isolated mode, since we only want the
  Standard Library, any code we explicitly pull in, and nothing else.
- Return a proper failure code.
