Youtube List Trimmer de Kevin

Adds a button that removes the youtube playlists and refreshes the tab.

Searches the active tab address for "youtube.com/watch" and if you're watching a video it then looks for "&list=".
If it finds a list the URL will be trimmed to remove the playlist part and everything after it, then it navigates to the video.

This effectively saves you the work of manually removing the list parts to not be annoyed by the autoplay features that are forced upon you by youtube playlists.
Only affects the current tab and will ignore any URL that does not contain "youtube.com/watch".
