PileMeister chaining and time limit in place.

- player cannot play more frequently than once every 60 seconds.
- player issuing chain option on deal will link to next hand.
Chaining fix, additional spec.
PileMeister break command added.
PileMeister hooked up to hubot.

Lots of tweaks needed to fill in the blanks in hubot and Dealer classes.
The OCP problem in Dealer and Hubot is all the more apparent now. Before
getting into refactoring that, I need better help and feedback to
players, since PileMeister is purty different.
