Ajaxified!

The subscriptions page has been ajaxified! You can now move subscriptions, display more or fewer subscriptions, create folders, rename folders, delete folders, unsubscribe, and check for updates without an annoying page refresh. And it looks great. Thank you, ajax! Perhaps most importantly, this little exercise has taught me, after several years of merely tolerating JavaScript, that the language actually does have some redeeming qualities. I've learned to appreciate the wild, wild west that is JavaScript development. I will probably add some other minor ajax features to other pages as well in the near future.
