Add host parameter to mitigate CORS issue (D7)

CORS Policy blocking is continuing to be a problem

I'm continuing to see problems with CORS policy blocking attempts to acquire the feed.

I've been chatting with the folks at the Github account that supports the Javascript library and apparently it's a Google issue where the images are hosted. The solution is to add a host parameter that randomizes part of the query that pulls the images. This parameter is part of recent versions of the jQuery Simple Instagram library. It's just a matter of enabling it.

I'll be adding that to the Dev branch shortly.

Cheers,
Andrew
