Short circuit swipe event handling for Special:Videos on mobile

@hakubo Video wants to disable swiping in the modal for the new Special:Videos page. It seems there's no elegant way to simply turn off paging. If I skip loading of the paging module, it will also fail to load content and because of the ad hoc nature of the events, it seems that there isn't a simple opportunity to 'unbind' the events on the main pager elements. Here is my solution to this request, although, I don't particularly like adding more conditions & complexity to an already pretty complex flow. Do you have any better suggestions?
