Add a game_state argument to decode_ui()

Some games would like a way to check that the parameters in the encoded
UI string are consistent with the game parameters.  Since this might
depend on the current state of the game (this being what changed_state()
is for), implement this by adding a game_state parameter to decode_ui().
Nothing currently uses it, though Guess usefully could.
