Module-accessible undo checkpoint

[riverwanderer]

Create a new hotkey driven component, essentially a simplified Action button or an option on the Action Button, that will disable UnDo beyond the point at which that action is taken. This feature would be of use in module design at certain checkpoints where accidental undos irrevocably compromise the gameflow - typically, when a card is drawn.

A code fragment that might achieve this (taken from GameRefresher.java is:

 {
        final BasicLogger log = GameModule.getGameModule().getBasicLogger();
        if (log != null) {
          log.blockUndo(1);
        }
