- validate 'nextsector' fields on walls.

Browse source 
Build utterly relied on the map having these right and put the entire responsibility on the mapper.
There's maps, however which have bad values here causing either render glitches or crashes so these bad indices need to be fixed.
Two good examples where this causes problems are RR's E3L1 and the second map of SW's Last Warrior mod where this even glitches in Polymost.
