Integrate Website's To Watch List

Ok, go this re-based and tested. 
Yes, it can, but I'm specifically just pulling in movies in the update_towatch routine since it would seem odd to have subscriptions and sync episodes from the to watch list.  So you can browse the watch list for TV shows but they wont' get synced into your library.  If we wanted to go whole-hog on website integration someday we could scrap the subscription database and use the TV to watch list instead but I'm not sure that's really a rational thought.
