Base view and template for embedded POI.

Derived from the POI detail view.
Initial attempt to use the embedded POI in course detail view.
Minimalist working example.
Cleaned embedded POI view.

Basic but it works.
Use embedded POI in Courses/course details.
Refactoring to pass an element to the EmbeddedPoiView rather than passing an ID.
Added map view to embedded_poi (proof of concept).

It seems that adding styling in <div style""> is not the good way to do it
Style embedded map in scss.
Center the map on the poi by default.
Corrected hints from jshint.
Minor styling changes
Updated to make embedded maps non-interactive
