Updated UI & 1 More Track

Updated "Hey DJ" with a new, more modern UI. Also added a new chillout track.

If you enjoy the project but want more Trax, a new Drum N Bass track is coming in the next update! Please feel free to share any thoughts you have about "Hey DJ", good or bad.

For now, all loops used in the player are in WAV format. This might change soon/later, but for now, it might take some time/bandwidth to download it to cache the first time you play it in the browser.
