Single page map scaffolding view and html. Upgrade (kinda) to Leaflet…

…1.0 (#1077)

* Single page map scaffolding view and html. Upgrade single page to Leaflet 1.0
- ProjectMap will server as the main view for all project pages
- Side pannel can be displayed or hidden by switching between detail-hidden and detail-display
- Upgrade JUST project_map.html to Leaflet 1.0. Since other pages will be absorbed by this one, I am putting off the full upgrade until the other views have been reworked.
- Currently only standard tests for ProjectMapView. Will add more as more functionality is added.
- Removed L.Deflate temporarily. Running into issues with upgrade to leaflet 1.0

* ripped out django-leaflet. set up js/smap/

cadasta/config/settings/default.py
