Install django watson during provisioning.
Add ``map`` and ``Locations`` models.

https://github.com/madewithbytes/us_ignite/issues/155

The Locations are displayed in a single map, they can
be categorized and the icon can be set for the Category
or an specific location.
Add admin section for the ``map`` models.

Add views to list the ``Locations`` in a map.

https://github.com/madewithbytes/us_ignite/issues/155

The rendering of the map is triggered in a callback from the
JSON endpoint that list all the available ``Locations``.

The endpoint is available at ``/maps/locations.json``, and the
callback is ``maps.render``. The objects returned are sanitized
and don't output any more information than the maps needs.
