Feature/mfr geo

This is a new feature to render geospatial data. Currently renders geojson files with optional simplestyle fields to customize symbology. This is already working for geojson files and can be extended for more geospatial file types.
I tried downloading mapbox.js and mapbox.css but I could not get the map to render, I believe the mapbox CDN provides relative links on there server that mapbox.js calls so it may be hard to recreate the needed assets or easy and I am not familiar enough with using JavaScript API's. Also, using the content delivery network is stated as the recommended access method for mapbox.js in their documentation. The whole API is only 30KB zipped so it is quickly delivered from the CDN. If it is requirement to serve the assets from the mfr, I can take another look at it.
