    Synchronize with Sent Mail immed. after sending one: Refs bug #714450
    
    This doesn't completely solve bug #714450 but it does display a reply
    or forwarded message more quickly in a conversation (rather than wait
    for the Account object to signal that a Folder's contents has changed,
    which is polled and may take minutes to notice).
    
    This also slightly rearranges the priority order for background
    synchronization, recognizing that some Folders (Drafts, Sent Mail) are
    as active as All Mail but quicker to synchronize with (i.e. don't wait
    for All Mail to complete synchronization before checking those).
