Merge pull request #7 from mmccurdy07/master

Artwork tweaks, logs for performance debugging
If used as a secondary agent, we already have a unique id for every movie (the IMDB id coming from the primary agent). Use this to save 1 http request in the search method.
Set original title only if different from title.
Use country specific release date if available.
Return good results and release years even if media.year is null.  Logic to differentiate many similar/identical search results based on TMDB "popularity."
