Change the semantics of sim_is_active to return a t_bool (which was 98% of how it was used), and added new sim_activate_time to return the time a unit will be activated (the value previously returned). This affected a handful of used of sim_is_active in device implementations which were adjusted to use the sim_activate_time API.
