First cut at capistrano deploy

Final deploy recipe for capistrano
Go easier on browser CPU

The turn indicator was being redrawn as an animation frame, which caused

70-80 percent.  Since it only changes when a player places a piece, I've
moved the updating to the click handler, and now my CPU is happy.
