#24 Don't completely ignore black list directories

Currently a list of directories is blacklisted.  These include directories
like sample, subs, proof etc.  They contain small samples of the video in
question and are generally ignored by the user.  The script skips these
folders.

The script should not skip these folders but add them to the DB and mark
them as non-browsable.  This should clean up the video listing when
directory mode is enabled.
