Functional SoledadBackedAccount and LeapMailboxes

The imap service is launched from the tac file,
and still needs some information to be provided in separate
config files that stub much of the initialization parameters.

working fetch and store methods.
tested with offlineimap and thunderbird.
several mailboxes might be broken.
