When loading map w/ oob sectnum sprites, make them have sect. 0 if updatesector fails.
Previously, if the sprite turned really out to be in void space, either freelist inconsistency (before the list rewrite) or oob access (now) would happen. Also add an bound-checking assert() for insertsprite's sectnum argument (it's not a bound check!) git-svn-id: https://svn.eduke32.com/eduke32@2480 1a8010ca-5511-0410-912e-c29ae57300e0
