3-Day Weekend Sprint

Does a ton of stuff that's probably irresponsible to commit all at one time. 
I was a naughty girl racing through development without stopping to commit. 

* Redoes the association between Feeds and Photos
* Adds a new Search object
* Adds a wrapper for the Instagram API that searches by tag or by username
* Sets up lots of basic CRUD views & routes for photos, feeds, searches
* Different layout for login/logout & the logged in user
* Basic outline of style framework
