I removed the media database in an earlier commit, but it's now necessary again as I decided to add native media syncing to AnkiWeb. This time, the DB is stored in the media folder rather than with the deck. This means we avoid sending it in a full sync, and makes deck backups faster. The DB is a cache of file modtimes and checksums. When findChanges() is called, the code checks to see which files were added, changed or deleted since the last time, and updates the log of changes. Because the scanning step and log retrieval is separate, it's possible to do the scanning in the background if the need arises. If the DB is deleted by the user, Anki will forget any deletions, and add all the files back to the DB the next time it's accessed. File changes are recorded as a delete + add. media.addFile() could be optimized in the future to log media added manually by the user, allowing us to skip the full directory scan in cases where the only changes were manually added media.
