[Feature Request]Directory/File Blacklisting Plugin

I would like the ability to have decibel ignore the existence of a directory or file in my directory structure. The option to do this should be available via right click and clearing the blacklist should also be possible.

Rationale: After suffering too many windows issues and losing some of her music files my significant other has 'suggested' that we integrate our music collections. Our music tastes are somewhat similar but there are a few 'artists' that I just don't want in my collection so I originally had placed those albums in a separate other_peoples_music directory. After using it for a couple of weeks this solution just didn't work for her and now I have Five and the Backstreet Boys in my MP3 folder. I only really play my music through Decibel so the easiest solution for me would be to have this sort of blacklisting functionality added.

I would be willing to try and add this myself but I can't find a location to download the latest source for decibel.
