increase_timeout_because_unit_moved()

void increase_timeout_because_unit_moved

(

void

)

adjusts game.seconds_to_turn_done when enemy moves a unit, we see it and the remaining timeout is smaller than the timeoutaddenemymove option.

It's possible to use a similar function to do that per-player. In theory there should be a separate timeout for each player and the added time should only go onto the victim's timer.
