Mail formatter rewrite - convert some plugins to modules

audio-inline, itip-formatter, prefer-plain, tnef-attachments
and vcard-inline plugins were converted to modules so that they
can fit into concept of the new formatter.

Every module still installs .eplug file, because there is no
suitable API at the moment to register plugins to the plugins dialog
and to extend the Preferences dialog.
