Ability to blacklist ads that got missed from browser

Transporting a feature request from GitHub.

That would be nice to have a browser extension to report back ads that the pihole didn't catch. I love pihole and it catches most ads, but it would be nice to right click and block ads that come through. This is similar to the right click, block functionality of Ad Block Plus.

This may be partially implemented with this, but there was still some discussion about the request on GitHub. It's easier for us to track feature requests here since they are votable.
