Preserve timestamps when updating rating & play counts

[mncroc]

I use the file's modified date when editing tags (e.g. in MP3Tag) to tell when I last updated content of tags. I'd love an option to tell SMP to not update the modification date for less important data like ratings and play counts. I LOVE that you can save that data to the file, but wish it didn't update the timestamp.

I noticed an older request about the same for play counts...

Thanks!
