handle self in content+discussion

  1. confusingly, in searches, "_self" refers to the card on the left.  That's why it breaks in the search above that's a simple card.
  2. _whole doesn't break because WQL doesn't recognize the term "_whole" at all.  It's just treating it like a string.
  3. what would we want _self to mean in this context?  the card's name?  the card's content?  I think there's already another ticket about this.

make card name referenceable in WQL?
