Resolve "Geolocalization"
This MR implements content geolocalization, without filters.
It was based on work done on the old website, but the code was modified substantially:
- Every JS is now CoffeeScript
- We refactored the code to separate it into classes
- Refactored the functions to be more readable and cohesive
- Implemented actions for retrieving the share button and box partials
Closes #90 (moved)
