Google OAuth 2.0 setup

Prior to Moodle 2.3, Google Docs and Picasa repository plugins and portfolio plugins could be used without any configuration or registration with Google. In April 2012, Google Announced to web application developers that they would be deprecated the service which Moodle was using to communicate with Google and strongly advised developers to move away from it. As a response to this change with Google's service, Moodle switched to use a new system for communicating with Google called 'OAuth 2.0', starting with Moodle 2.3. The OAuth 2.0 system providers and a better security system and more friendly experience to Moodle users, though it requires some additional configuration in Moodle.
