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. 
Instead of including the CSS file here, we typically include CSS files via Sass `@import` statements. The best way to figure out how to include this file as per the other files is just grep for another file, for example:

Since the `_points.scss` file needs to be included on every page too (since it's rendered on the header bar too), you can also include your search bar stylesheet the same way (by importing in `_base.scss`).
