containers and objects in special level descriptions

On mazelike levels, containers had to be listed before their objects.  But,
for roomfilled levels, containers had to be listed _after_ the objects.  All
our current levels that use containers with objects are mazelike, so I
changed the room behavior, updating the comment in lev_comp.y to match.
Other items/monsters are still processed in reverse on roomfilled special
levels, but I think this is OK.
