New music tag search, direct downloads and html5 previews

The music catalogue has been re-tagged and recoded:
- Now you can search for a combo of multiple tags at once! Visit the music tag search page to learn more.
- Logged in clients can download high-res mp3 and wav files directly. Login at the music server and then return to the music catalogue and voila downloads available at lightning speed!
- All audio previews has been recoded as html5 embedded mp3 audio in the catalogue, meaning you can preview clips on your iPad, iPhone and other mobile devices as well! Most internet browsers are also supported (currently not Firefox & Opera). This is also a way of adjusting to new future releases on the tablet market. Music server high-res previews will remain flash based. The old flash players are still available at http://niklasaman.com/music/download-demos/.
