Title: Bug 796082 - store cached album image to metadata

1. Store cached thumbnail to metadata, and thumbnails are resized to the size of man tile (210 x 210).
2. This is how the gallery/js/MetadataParser.js handles the thumbnails for metadata, I also used the same way in music for album art parsing.
3. A patch for shared/js/mediadb.js
