New tourney Option

[tony stack]

I suggest an option on tourneys to allow the directors of tourney a authority to undo the bidding/play at a given table by simply clicking the "undo" button, as is allowed by the teacher at a teaching table. It is intended that this option be seperate from the "allow undos" check box. Tourneys have the option to: only accept undos if a director has been to table and allows it, Or tourney could allow players, and directors to accept undos , allow players (only) to undo, or absolutly forbid undos.
