Creates an RSS url under each video. The way youtube's UI now works, however, this url is only valid after a refresh, so this link reminds you to refresh to get the RSS url. If there's a way to get the RSS feed for a channel without a refresh, I haven't found it; everything in the global javascript namespace is only good for the first page load.

Maybe somebody else will come up with a more elaborate way to do this, like loading another instance of youtube in an iframe? But this script works well enough for me.
