"Logical stops" in the interrupt gui

[asd2769]

TL;DR

The interrupt "Add station" GUI lets the user name a not yet existent stop that doesn't show up in the stops list.

What?

When a user names a stop in the "Add Station" GUI, it should create a ghost [0] station stop to be easily selected onto a stop or inside other train schedules.

Example current behavior

Logical refuel stop created in the interrupt GUI does not show up on the stops list.

Example new behavior

Logical refuel stop in the GUI, with a 0 tag to signify no physical station with the name.

The interrupt "Add Station" text field should also be added to the normal schedule GUI for consistency.

Why?

Creating a logical stop before the physical one is built would be a nice QOL feature. For example, we could add a stop for a not yet built fuel depot or an intermediate product stop.
