Notification working on local test files

Almost there! And it turns out this is a Chrome App, not an extension.
(Noob!)

- Got notification working again
- Got list of matches on the notification list  (SR and SysID)
- Got listeners working and "Go to DH Q" button working

To do:
- Move notification matches from list to buttons that will take to the
SR

- Use real webpage and add delay to have it load completely before
parsing.

- Go live!
