Changed from vibrant coloured indication of suspect videos to reducing their opacity, which meshes much more with the intended effect.

Add support for videos on search screen. Fix problem that may have prevented highlight updates when looping over mutations.

Target changed DOM nodes better to improve accuracy of highlight effect. Script was occasionally ignoring updates to elements.

Fixed a problem where warning styles would not be removed when a page updates the visible video links, specifically on a video page when clicking on an up next or related video link.
