Search with typeahead

Switched everything over to use Typeahead.js and Bloodhound.js. Tried to keep proper formatting intact, but a second look would be appreciated. Will post screenshots as well. 
Why do you need to animate both `.search-div` and `.twitter-typeahead`? If you absolutely have to, you can select multiple elements in your jQuery selector so as not to duplicate the code above (i.e. `$('.twitter-typeahead, .search-div')`).
