OAuth2 authorize URL extra params + Google example

[mccahill]

...to illustrate using extra parameters

Google seems to like having a scope parameter specified in the Oauth2 authorize URL, so I added an extra parameters option to the description. There is also a working example of using OAuth2 against one of the Google Calendar APIs

this looks like a good addition. it's been around a little while but it seems like a good thing to merge with a few modifications. I'd think the parameter should be configurable for both authorize and access_token. I'm going to have to double check if we need permission to add the google definition.

Here's an example of some additions :

  "oauth":{
     "options":{
        "authorize":{
           "scope": "read, write, execute"
        },
        "access_token": {
            "redirect_uri": "http://example.com/theuri"
        }
     }
  }
