undo

[glilienthal]

Firstly, thanks for the awesome mode. My factories would lack so many spaghetti qualities without your work!

Secondly, Some of beltrouters designs are just too cluttery, and very cumbersome to remove. It'd be great to have either an undo, or an option that a path needs to be accepted before it is converted to ghosts. That way I could try, see whether it's ok, or whether I better make some space.

Thank you very much.

Sounds good! Many people have requested supporting undo function. I think I can add support for that in next version :D
