Title: Update README.md

I know that the `approval_prompt` and `access_type` params can be set to empty strings (anything other than nil, really) but I defined a specific value, according to [Google's documentation](https://developers.google.com/accounts/docs/OAuth2WebServer#formingtheurl). Hope you don't mind. Maybe you could even change this in the future to match the spec?
