Quite a few levels did not have a REJECT lump and were using null
(all-zero) REJECT lumps instead. I ran these through RMB so that all
the levels would have efficient REJECT lumps.
Moved from SourceForge; also levels/sargebaldy/hellkeep.txt had some
weird end of lines (various mix of CRLF, LFCR), that's fixed.
