This code had to be added in case a user has cbs/originals open in 1 browser and cbs.com/primetime/cold_case/video/ open for example. In this case, because i couldn't isolate the 'site' cookie to /originals only because the video player can only read cookies at the root level, in case the 'site cookie is a live for a user because of the 2 video pages open at the same time, the ;site cookie needs to be deleted on non cbs/originals/video video pages.
	//i had to add this function call due to the webisode central new 'site' cookie. For centered paged, the above line of code is applied in sitecommon/includes/video/centered/player.php. For non nentered pages it is applied here as all non centered pages use a different video player which required type=nobc to be appended to the adv cookie, so this is the easiest place to delete the 'site' cookie for non centered video pages
