handling of {DEC,IBM,MAC}graphics options

Browse Source 
Fix the problems From a bug report.  So having
  OPTIONS=IBMgraphcs
  OPTIONS=noDECgraphics
would yield an ASCII display instead of showing IBMgraphics, but IBMgraphics
flag in the Options list would falsely show as on.  Manually toggling it off
put things back into sync.

     Avoiding the false setting is completely trivial.  And fixing the
inappropriate override turns out to be easy too, unless I've bungled this.
One thing it does not do is try to warn about attempts to set conflicting
options like
  OPTIONS=IBMgraphcs
  OPTIONS=DECgraphics
Fixing that seems to be too messy to bother with, particularly since the
game runs ok (leaving the setting handled last in place).
