Fix for issue #21 Edit A User fails to update the database correctly.
This is a rewrite but given a new file name.  It will replace user-edit-any.php and user-edit-self.php.
It has not been extensivly tested but I wanted to get checked in so there aren't any other attempts
to fix the old user edit scripts.  From the UI  Users > Edit User Account.  If you are an admin you have
the ability to edit any user, including yourself.  If you are not an admin, you can only edit yourself.
