1412 new business locations

Added endpoint for new business locations. I got the text from [the issue on citygram-services](https://github.com/citygram/citygram-services/issues/25).

One note, we might want to add the `location_start_date` to the message to add a little context.

This PR also has some minor tweaking of where the adapter files should live, and I simplified how the homepage is generated.
