Demo

I made a bunch of changes to the demo app over the w/e.

Summary:
- Controllers now return the suggest 'payload' hash with the 'name' hash merged in.
- Started working on the search endpoint but ended up reverting most of it.
- Suggester now makes a new request when the map view changes (so it auto-updates as you look around)
- Added some 'shortcuts' at the top left of the webview to skip to major cities around the world.
- Changed some of the icons in the auto-complete, added new ones for admin levels.
- Re-enabled the toggles in the bottom right corner for more layers.
- Added a function to make sure only one pin is added to the map per unique id.
- Changed the POI popup to have more detailed information.
