imdb_list import from HTML  page instead RSS feed

imdb watchlist rss feed is broken right now and can't be sure when and
if it will be back up. this will now parse the html page for movies and
create entries.
Hmm, looks like we used to have the year in the title in parentheses. I think it would be pretty easy to grab that and add it back in to the title, we could also populate the `imdb_year` field with it as well.
