Preliminary support for adding favorites in Google Photos.

Please comment on this code.

Tho it doesn't work, it gives me a HTTP 500 INTERNAL SERVER error.

How do I see exactly what HTTP is getting sent upstream?

I don't think this approach is good, since "favorites" are not a general concept across all data sources; it's Google Photos-specific. Instead, all (or mostly all) of the changes should be within the googlephotos package specifically. I haven't looked at this code in a while and I'm short on time right now but that's definitely more likely to be accepted. :)

To see the HTTP requests that are getting sent, you can do fmt.Printf("%#v", req) in the right place in the code where the request is made. See the googlephotos package.

Thanks for working on this!

Closing due to inactivity; needs to take a new approach as well.
