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. 
I don't think we need handlebars... we use underscore.js for templating, and we don't need to bring in another library (I know [the example here](http://twitter.github.io/typeahead.js/examples/#custom-templates) uses Handlebars but we already use underscore.js).
