Make makepalookup() accept NULL for 'remapbuf', meaning "use identity mapping".

Browse source 
Also,
 - use this in game.c and astub.c palookup loading code
 - when makepalookup() is passed a 0 palnum, return early.  This means that
   'fogpal' will silently fail when attempting to change pal 0.
 - in 'makepalookup' DEF command, error out if passed a pal of 0.
