Make mini_float the default; add a no_exits tag instead.

There have been so many problems with minivaults not having exits that
this is an easier solution than the alternative.

You're still allowed to explicitly place exits, of course, in which case
floating exits go away.

There are a couple of other small tweaks to the level documentation here
as well.
