Many assorted changes

-Set paginate_by to 20 for full view, and 100 for slim view.

-Set default order on podcast pages to "ordered".

-Added is_hidden attribute to Podcast model, so that I can select to
hide certain podcasts from the podcast queue (podcast's that do not yet
have multimedia available on podverse).

-Close YouTube videos as soon as they are finished with the
event.target.destroy() function.

-Added a "skip" button to quotes.

-Added "alphabetical_title" to Podcast, and override the Podcast save()
method so podcasts are not sorted by "The, A, An".
