FIX: Discard passengers/goods in excess of 6,5535 packets when saving to avoid corrupted saved games (this discarding will not occur when the save game vesrion is incremented to 11).
ADD: The paths are re-checked every X steps, which can be set in simuconf.tab by reroute_check_interval_steps = X. The default of 8192 will be imposed on all network games until a version increment. This enails updating the paths every 2 game hours or so at 250m/tile.
CHANGE: If passengers/goods have been waiting at a stop for more than twice the registered waiting time for their next transfer, their waiting time is recorded forthwith to prevent excessively low waiting times being retained, skewing path finding.
