* Callback method for the Google Calendar API authorization process.

* Once the user grants consent with his Google Calendar data usage, the Google
* OAuth service will redirect him back in this page. Here we are going to store
* the refresh token, because this is what will be used to generate access tokens
* in the future.
*
* IMPORTANT! Because it is necessary to authorize the application
* using the web server flow (see official documentation of OAuth), every
* Easy!Appointments installation should use its own calendar api key. So in every
* api console account, the "http://path-to-e!a/google/oauth_callback" should be
* included in an allowed redirect url.
