FS#385 - Count Vehicles in Player Station List
This patch changes the player station list, so it displays the number of vehicles which have that station in its order list.
Technically it uses 5 counters in the station struct, named num_vehicles. These counters get updated, when the StationList is resorted.
In case of an order-change, the station (re)sorting is triggered.
If there is a facility for a certain vehicle type, but not vehicle going to that station, the counter is written as a red zero.
Currently there is norma-font size used. I would prefer tinyfont, but it is almost unreadable.
Patch is attached.
