helixhorned b7df5ffa5f Big clean up in defs.c and related content. The usual stuff... 
- factor out many identical checks in a convenient function; some messages
  may read slightly differently now and tile ranges may be handled more strictly
  (error out if one of the limits is invalid)
- factor out two instances of identical (up to one arg) code into
  tile_from_truecolpic
- factor out setting picsiz[] and stuff into set_picsizanm
- some checks
- Make "undefmodelof" non-functional and warn.
- in "animtilerange", if the tile difference is >= 64, error out since we
  can't store it in picanm[]
