Added a new callback "callbackOnWait" to trigger various effects when an Actor takes no action in a turn.  Added to Actor:waitTurn in place of "callbackOnRest."   New function Player:restCheck (an overload of engine/interface/PlayerRest:restCheck) triggers "callbackOnWait" when successfully resting.

The recovery effects of Spacetime Tuning and Throwing Knives use the "callbackOnWait" callback.

NPCs that know Spacetime Tuning will automatically set an appropriate preferred paradox value periodically (at 100 below the anomaly threshold).

Added the game.turn to the output of a number of AI debugging statements.

Fixed a bug where Chants and Hymns could be learned without also gaining the appropriate resource pool.
