Randy Heit d2c275bbb3 - Changed FScanner so that opening a lump gives the complete wad+lump name
rather than a generic one, so identifying errors among files that all have
  the same lump name no longer involves any degree of guesswork in
  determining exactly which file the error occurred in.
- Added a check to S_ParseSndSeq() for SNDSEQ lumps with unterminated final
  sequences.
- Fixed: Parts of s_sndseq.cpp that scan the Sequences array need NULL
  pointer checks, in case an improper sequence was encountered during
  parsing but not early enough to avoid creating a slot for it in the array.
