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.
pythonic way would be to use a for loop, like `for current_page in xrange(number_of_pages)` instead of declaring and manually incrementing a counter variable.

Also, that would be a 0 based counter, so it'd change some of your math down below.
