YouTube tests disabling videos for people using ad blockers

youtube.com##+js(set,yt.config_.openPopupConfig.supportedPopups.adBlockMessageViewModel, false)
youtube.com##+js(set,Object.prototype.adBlocksFound, 0)
youtube.com##+js(set,ytplayer.config.args.raw_player_response.adPlacements, [])
youtube.com##+js(set,Object.prototype.hasAllowedInstreamAd, true)

Here it is in text format so ya'll don't have to type it out. I haven't verified that it works but by the looks of it it just makes the Adblock sensor report a false negative. [edit, fixed some spacings that sneaked it's way into the filter upon copying it earlier.]
