Background page + persistent settings data

Successfully split my JS script into a background script that gets the
data and stores it and a script that runs on page loaf to render it.

Things left to do:
- Make sure page renders once again after new data is discovered
(should only be an issue during initial load, as new data should update
every 10 minutes after that.
- refresh button
- loading animation
- name of location (google maps API?)
- author credentials
