2.22 Exif Tags, Filtering, and Blurbox settings

• Added Blurbox settings to settings page
• Expanded blurbox margin (Thanks qwksilver for the suggestion/demo work!)
  -Added Exif Tag work (works only on .jpg, hit 'e' key to show Title/Artist for now)
  -Added Exif filtering (inclusive filter only currently. Supports multiple tags using semicolons. On 'playlist' tab in web UI)
  Some stability improvements.

Pre release still. I have some work to do on the fades/performance to get to release quality.
