...to support an arbitrary number of connections for rails, which leads to these new features:
- switches now get recognized by the trackworker correctly
- ability to add real rail crosses
During this, I also rewrote the rail registering system and the conway function (important part of path prediction)
Note, developers: the track preset format changed, you might need to rewrite them according to the presets in tracks.lua if you wrote your own
(possibly breaks advcarts)
This finally fixes the need to rotate atc rails and bumpers.
Also prefers rotation that is closer to the player's look dir (placed bumpers will face the player)
