Improve distinction of movies and series

[KilianB]

As mentioned in #1 the code sometimes is not able to distinguish between series and movies. This is due to the fact of inconsistent formatting on netfllix side (or rather them not providing additional information).

I don't think much can be done on the regex part but maybe we can query for series and movies and see which returns a higher score on the trakt.tv similarity score.

An interesting approach would be in case of ambiguity to use the title perform a google search appended with "movie" and "series" and see which returns more results?
