Fixed show production issue

The plugin was no longer producing shows, because they removed the list of shows from the full episode and video clip pages.

Changed plugin to pull show list from the main show page again. Added an exclusion list for those shows that either do not have videos or do not work with the plugin. And rewrote function for producing full episode and video to work with this new pull method.

I also added a new function to produce videos for Specials that do not work within the regular plugin framework. Currently it works with Comic-Con and Guy Choice Awards.
