* Removed default_sent_directory(), and introduced

default_mail{_in|_out}_directory() methods in the BPrivate namespace.
* Used these methods in the inbound/outbound protocols.
* Moved WriteMessageFile() into the BPrivate namespace as well, and put its
  prototype into a new header MailPrivate.h along with the new directory
  getters.
* Removed the automatic copy to the sent directory again, and only have one
  directory for incoming mail. Incidentally, this fixed #7509, although the
  underlying filter restriction remains.
* Automatic whitespace cleanups, some style cleanups. Sorry for the mess.
