Control refactor + MVP IE support

With this PR we have:
- Moved all markup into JS
- Ditched nice things like Geomicons in favor of plain old PNGs for the sake of IE
- Updated our handling of geolocation.

As a result, we now have basic IE 8 support—the map loads, the data loads, the Google Places API allows you to search for locations near an address, and the print styling still works. Lots of improvements to be made, but this is the baseline we need to deliver. 

This PR should close #87 and #88
