This is a patch against Xwadtools-20010615 that brings wadsprit
up to version 1.5. Changes :

  - Recognise SS_START.
  - Between S_START/SS_START and S_END, ignore any spurious
    S_START or SS_START.
  - Outside S_START/SS_START and S_END, ignore any spurious
    S_END.
  - Case-insensitive lump name comparison (E.G. works with
    "ss_start").
  - Use get_lump_by_num() instead of get_lump_by_name() (safer
    and faster).
