Add ml.utils module for mlMaps

The ml.utils module is designed to hold various utilities.  Currently it contains a mapping service and a capitalize filter.

The slush template has been updated to include the module js file, inject the module into the app, and show some basic configuration of the mapping service.  Details on the module itself are found at the github repo, and a demo page is found here:
