Subject: Update adds prboom's high resolution support, also makes the scaling
 for platforms w/ resolution less then 320x200 much nicer.  IDoom's lookup
 table code has been removed.  Also fixed a pallete bug.  Some graphic errors
 are present in menu and status bar.  Also updates some headers and output
 formatting.
