REVISION SUMMARY
  For reading, writing, and eventually getting notified of changes to settings.
  Promise-based API taking into account defaults values.

TEST PLAN
  - Settings page loads and write settings fine
  - Content script loads settings fine
  - Extension script loads settings fine and sends them to the host
  
  Probably needs some Firefox ESR 60 testing to see whether it can deal with the `class` stuff...

REPOSITORY
  R856 Plasma Browser Integration
