When loading a game, DON'T restore 'adult' TV tiles. This fixes the recent

Browse source 
crashes.

Usually, after loading a game, some wall tiles are tweaked depending on whether
adult mode is enabled or not.  If it's not, those wall picnums are replaced
with blank or broken screens.  If it is, they are restored from the wall's
.extra member.  Apparently though, Mapster32 leaves some .extra members
floating around even after deleting a TROR nextwall link (it's used as the
'lower wall index').  Because MAXWALLS is greater than MAXTILES, this may
produce out-of-bounds accesses and corrupt memory (besides setting wall
tilenums to nonsensical values) later in the game.

Other than that, the change only affects loading savegames created with adult
mode OFF. Kinky TV screenies simply won't be restored then.
