Aiguillage reverse direction.

Let's see how this works out with my printer down at the moment, so I'll test it manually first and then share the results with you all. If anyone manages to give it a try before me, please do let me know. This script should allow us to run the original part in reverse as well, which is a great bonus. It should basically just slide over the original arrow lane changer without any issues.
