Should we add this to one of the versioned files, too? If it's only used in the scanner (for now) we can probably get away adding it to the latest existing up files, avoiding another full wipe & rescan.

That reminds me, I changed the INSERT to check tracks using coverid rather than cover, in case the user has updated an image without changing the file name. So I don't think this index is required any more.
