register changes made using Mp3 File Information

When I use the [Mp3 Info] button, it is great that changes made in the Filename textbox actually rename the file once the [Ok] button is pressed. However, once that [Mp3 Info] dialog is closed, the filename in the existing list of Mp3 files is *not* updated to reflect the rename that just occurred, and, if the (renamed) file is selected, no functions will work on it because the "file is not found."

Need to update the filename in the list if the filename is changed using the [Mp3 Info] dialog.
