First stage of the storage schema rewrite.
* Separates between flags, docs, body and attachment docs. * Implement IMessageCopier interface: move and have fun! This little change is known to push forward our beloved architect emotional rollercoster. * Message deduplication. * It also fixes a hidden bug that was rendering the multipart mime interface useless (yes, the "True" parameter in the parsestr method). * Does not handle well nested attachs, includes dirty workaround that flattens them. * Includes chiiph's patch for rc2: * return deferred from addMessage * convert StringIO types to string * remove unneeded yields from the chain of deferreds in fetcher
