[Python-ideas] Implement `itertools.permutations.__getitem__` and `itertools.permutations.index`

[Ram Rachum]

I'm probably going to implement it in my python_toolbox package. I already
implemented 30% and it's really cool. It's at the point where I doubt that
I want it in the stdlib because I've gotten so much awesome functionality
into it and I'd hate to (a) have 80% of it stripped and (b) have the class
names changed to be non-Pythonic :)
