Previously, we instanciated an MappedImapFolder, and would cleverly (too
cleverly?) invoke methods on it casting it to an IMAPFolder by calling
methods such as: self._mb.cachemessages(self) where self._MB is the class
IMAPFolder and self and instance of MappedImapFolder. If
e.g. cachemessages() invokes a method uidexists() which exists for
MappedImapFolder, but not directly in IMAPFolder, I am not sure if
Python would at some point attempt to use the method of the wrong class.
Also, this leads to some twisted thinking as our class would in same
cases act as an IMAPFolder and in some cases as an MappedImapFOlder and
it is not always clear if we mean REMOTE UID or LOCAL UID.
This commit simplifies the class, by a)doing away with the complex Mixin
construct and directly inheriting from IMAPFOlder (so we get all the
IMAPFOlder methods that we can inherit). We instantiate self._mb as a
new instance of IMAPFolder which represents the local IMAP using local
UIDs, separating the MappedIMAPFolder construct logically from the
IMAPFolder somewhat.
In the long run, I would like to remove self._mb completely and simply
override any method that needs overriding, but let us take small and
understandable baby steps here.

During a sync run, someone might remove or move IMAP messages. As we
only cache the list of UIDs in the beginning, we might be requesting
UIDs that don't exist anymore. Protect folder.IMAP.getmessage() against
the response that we get when we ask for unknown UIDs.
Also, if the server responds with anything else than "OK", (eg. Gmail
seems to be saying frequently ['NO', 'Dave I can't let you do that now']
:-) so we should also be throwing OfflineImapErrors here rather than
AssertionErrors.

I discovered that we do not run ui.terminate in all circumstances, so
make sure that we call with properly at the end of each run (whether in
threaded or single-thread mode).
