This patch changes the mail directory of the user to ~/Mail if possible.
First, we try to create the Mail subdirectory, and then we check to see
if it exists. If it does, we use it as the user's mail directory. If not,
we use the user's real home directory as their mail directory. This is
useful for trying to un-clutter the user's home directory from all of
their mailbox folders and such. This has no effect on blackbox users.

This patch is UNTESTED. (well, it is kind of tested, but not tested in
this form..  I just ripped it out of a larger patch of mine and tossed
it up here.) If you get this to work for you e-mail me about it and I
can know that this works. Thank you.
