games/doom: fix idclev cheat in doom2 and final doom

a typo in st_stuff.c:ST_Responder prevents idclev (change level) cheat to work
in doom2 and final doom (gamemode == commercial): episode is set to 0, when
that's invalid, and ST_Responder just returns.
to test, while ingame type idclev, followed by:
. doom1: episode (1-3 or 1-4) then map number (1-9)
. doom2/final doom: map number (1-32)
incidentally, if the last digit typed is 1, the player's weapon will switch to
the fist, because of a different bug (basically kbdproc registering two events
when pressing a key, for 'c' and 'k' case).
