Currently, to my knowing the following types of mutliparts exist:
- floor (big mountains)
- buildings (= exits)
- pentagram teleporters
- monsters

I think monsters and buildings should be placed always ontop (like
all currently do). Teleporters should be placed ontop everything
except monsters.
Floor should probably be placed below everything else, but
that's hard to say. I could imagine wanting both to put sth below
and above it.

      will at least take care of the blocked and invisible flags.
     
     
Hm... Are you sure it is better to copy the values into the
body, rather than making the code always look at the head?
Since every body object has a pointer directly to the head,
I don't think this would cost any cpu time.

      In most cases, the head is blocked, but if that gets extended to all

True. Unfortunately, as long as we keep the current scheme of saving
only the multi-heads, the no_pass won't work for buildings anyways.
I do agree that this is a tricky problem. Walking over rooftops
of big buildings feels kinda odd.
