Fix error handling in folder.Base.copymessageto()

Browse Source 
This is a bug fix on several levels. 1) We were lacking the import of
OfflineImapError. 2) OfflineImap.ERROR.MESSAGE was misspelled as ERROR.Message.
3) COntinuing with the next message only worked in single-thread mode
(using debug) and not in multi-thread mode. The reason is that we were
invoking a new thread and catching Exceptions in the main thread. But
python immediately aborts if an Exception bubbles up to a thread start.
This was fixed by catching exceptions directly in copymessageto() which
is the new thread, rather than catching them in the main thread.
