"call train here" button in station GUI

[mp0011]

Mostly useful for "personal" trains, but also help with debugging automated ones...

When You open Train Stop GUI, there are list of "trains with this stop". With map and schedule for all trains.
If You want to call a train to that station, You must click train's map, and train's GUI appears.
Then, You must find (in possibly long list) station You are already at, click it, and then - click arrow to send train.

It would be simpler, if in Train Stop GUI were a button to call train directly to this station (not other with that name!).
Train will skip all stations in its schedule, and proceed directly to that station.
If there are more occurrences of that station in schedule, just advance schedule to first one.

This should also work from map view...

Simply:
- go to station (or find it on map).
- Click it to open GUI.
- Find train.
- Click "call train".
- Wait for a train.

instead of:
- go to station (or find it on map).
- Click it to open GUI.
- Find train.
- Open it's GUI
- Find station in trains schedule
- Mark it
- Click "go" arrow
- Pray the train do not go to other station with same name.
