Oodles of new functionality/features.

Each tagger runs in it’s own Thread. Tagging objects are all now
completely thread safe. AtomicParsley output is now routed to /dev/null
in favor of maintaining an internal process meter. Trakt.TV support is
now used along side iTunes as the primary source of metadata for both
Movies and TV Shows and TMDB and TVDB searches are no longer run. The
code is still floating around in case I decide to run it later, but for
now they’re turned off. The Trakt.TV Movie class now takes a year
parameter which can be used to quickly filter films (particularly
sequels and remakes) by the year in which they were released.
