Proper display of Artist - Title using the Filefield Formatter

I noticed that in the theme function for the filefield formatter, the artist and title information is passed as NULL to theme out the player. There are a few issues about it already posted, but most were closed and dormant.

I created a patch that properly extracts the artist and title from the file as long as the id3 module is installed. This should fix the issue for ppl who were not manually using the theme function, but where instead using the formatter.
