Save Rope State

[josemendez]

So I've made a little progress and I can get the rope to initialize correctly as long as I haven't extended it previously. If I save the state of a rope that was extended with the rope cursor, I cannot successfully restore the state correctly.

If your rope has been extended, things get quite complex. You need to store which particles are active, and any new constraints that have been generated by the cursor. Haven´t tried this use case myself to be honest, once I do I´ll come back with some more info.
