Fully working with local test files

What's new:

- Added app icon
- Notification to show, SR #, SysId and Cust. Name if only one match
- Notification button to go to DH Q if >1 match, to the SR if just 1.
- Got it to find matches even if one Q has the SysID with punctuation
(@, :) and the other doesn't.

To do:

- Wait for pages to completely load before searching for matches
- Use actual webpages instead of test files.
