Google Image API implemented 

Here is my stab at google image (custom search) api implementation. It's the paid api with free 100 searches daily.

Per 4541841, I had to disable autocomplete for Google because there is no API through custom search api. They do have another API but it's a different URL so I wasn't sure how to do that with the httpclient used in this project. 

Suggestion API: http://suggestqueries.google.com/complete/search?client=firefox&q=YOURQUERY

Also pulled your wrappers branch into master. Instagram and that endpoint class was a big help :) 

Google custom search requires a cx (search id) with the request. I'm sending it as the secret key. See 49e5d1a
