Initial subscription fix. Still does not always display the list from
the correct folder, and it currently does not update unread count on
subscriptions.
- chans now work with the new interface, still some bugs present
- chans do not have a sent folder anymore (you'll see sent messages in
the sent folder of the account you're sending it from)
- shows gateway parser results more accurately
- gateway class assigned dynamically
- inbox sort order is aware of what you click on and defaults to
ascending
