[Twisted-Python] Implementing OAuth in twisted.cred

[Laurens Van Houtven]

I was confused about the latest spec; see
https://datatracker.ietf.org/doc/draft-ietf-oauth-v2/

I'm trying to figure out what changed from OAuth v1, some things
appear more complex, some changes are pretty trivial, but there's a
lot of different people writing and editing it now (Yahoo!, Facebook,
Microsoft), so this is probably the one to look out for even though
it's still in draft.

cheers
