Subject: [PATCH] game_timing_state() now has access to the game_ui. This means
 that whether the timer is currently going is no longer solely dependent on
 the current game_state: it can be dependent on more persistent information
 stored in the game_ui. In particular, Mines now freezes the timer permanently
 once you complete a grid for the first time, so that you can then backtrack
 through your solution process without destroying the information about how
 long it took you the first time through.
