Implement Zin's Recite ability.

Note that it's a bit crude in some ways.  Also, there are minor issues:

* The check for whether a monster can be imprisoned is currently
  identical to the check for whether Recite will work on it.
* Recite effects are not applied to the imprisoned monster yet.
* The ability costs are roughly a midpoint between Vitalisation and
  Sanctuary.
* The documentation has been updated to mention Imprison, but it could
  probably be improved.
