Right now, nothing. Only MaildirRepository parses the config file to
assemble the dictionary (patch 1/3).

Not yet, and at first I didn't intend to since my IMAP repository is
configured as readonly, but considering that i'll eventually use notmuch
it will be inevitable.

So maybe __syncmessagesto_flags could check if the Maildir side
(regardless of being source or destination) has a mapping, and use the
reverse mapping if it is the source. Then, to fully support Maildir ->
IMAP, I'd have to check if/how offlineimap currently adds keywords to
messages. Comments welcome.
