Tiny change, make the edit redirect window scrollable if it's too big for the screen.

This release has:

- Dark mode support
- Double unescape urls in redirect matches
- Angular.js removed from UI code (not really a feature, just cleanup)
- Off/On Red/Green badge on icon to indicate addon status.
- New type of redirect, "HistoryState", that lets you redirect pages on Facebook, Twitter and others that modify the page with javascript and then push a new url to the address bar with the History api.

Remove sync option as it did not work well enough in Firefox.

Added the option to:

* Sync between machines using your Mozilla account
* Duplicate redirect
* Support imageset redirects.

Thanks to https://github.com/gkrishnaks for his submissions for this version!

Removed logging by default, added logging option to popup window.

No functional changes, only moving the addon to the new WebExtensions API.
