yt-share-cleaner

yt-share-cleaner is an extension that removes tracking from YouTube share links.

When using the `Share` button -> `Copy` button to copy the share link, YouTube adds a tracking portion to the URL.

To deal with this annoyance, yt-share-cleaner:

1. runs whenever the mouse is clicked
2. reads the contents of the clipboard
3. if the clipboard has a YouTube share link, remove the tracking portion and write the new URL to the clipboard
