Adds a few different train stops that make automatic deployment/deletion of trains possible.

It works in a bit of a roundabout way so make sure to look at the forum thread for info: https://forums.factorio.com/viewtopic.php?f=93&t=49689

Please also keep bug reports and feedback in the forum thread as I am much more likely to see it there.

Enjoy!
