Adds support for OAuth 2.0 authentication to web2py.
OAuth 2.0 spec: http://tools.ietf.org/html/rfc6749
*****************************
NOTE that this is a modified version from web2py 2.8.2. For full details on what has changed, see
https://github.com/OpenTreeOfLife/opentree/commits/master/oauth20_account.py
This file was patched (by jimallman, on 3/25/2014) to support redirection on proxied web2py servers.
