FS19 - Fill Level Limiter V1.0

This global vehicle specialization is added to most fillable vehicle such as trailers, trains and seeders.
The user is then free to set the maximum fill limit they wish the trailer to stop filling at. Very usefull if you only want to collect a set amount from a silo or buy point.
Limits are saved for each vehicle and can be reset whenever required in the GUI.
