Added Fissure, Intelligence checkboxes.  Fixed Correspondence tag (misspelled).  Subject filter now works in conjunction with checked tags.  Entire mail clearer now uses trash_messages_where() so is much faster and easier on RPCs.  Client::get_alliance_id() now uses the alliance ID passed in empire status block, so it's essentially instantaneous.  Because of fast alliance ID, the 'Relax' Status popup has been removed.
removed a .bak file that should not have been committed.
