    Bug #599792 - Anjal composer's Send button doesn't work after pressed Save Drafts button
    
    This is due to an old hack that hiding a composer means we're closing
    it so save_draft_done() destroys the composer after saved draft. But
    in Anjal, the composer widget is always hidden (since the editor is
    reparented to the tab), and will be wrongly destroyed by
    save_draft_done() when you clicked "Save Draft" button.
    
    This patch improved the old hack, by adding a new API
    e_msg_composer_request_close() that can be used to request closing a
    composer (so the old hack is no longer needed). Internally,
    composer->priv->application_exiting is used to store this exiting
    status.
    
    So by this we no longer use a composer's visibility to check whether
    we're to close it. When you no longer need a composer after saved
    draft, call e_msg_composer_request_close() before sending the
    save-draft signal.
