man: updated configuration manual pages (maildir.* -> mailbox.*).

VMM/maillocation: MailLocation.__init__(): take a 'format' name, instead of a 'directory' name. - added function known_format() to the module. VMM/Account: Adjusted to above changes.

VMM/Handler: adjusted Handler.aliasAdd() to the API changes of the Alias class. Also use get_gid from the Domain module to get the gid of a domain. We don't need complete Domain object, only the gid.
