- Made folder/Maildir.py/deletemessage() more tolerant if a message asked to be deleted already has been. - In Base.py/copymessageto(), no longer bother calling getmessage() unless a folder's storemessages() returns true. This will also help with syncing to LocalStatus if the user deleted messages in the Maildir since the cachemessagelist() was called.
