Filefield_paths does not accept user tokens while filefield does

I was using user tokens in filefield (see filefield_widget_file_path() in filefield_widget.inc) and was suprised to see that support was missing in filefield_paths. If I'm not mistaken it should be fairly simple to add a similar token_replace call to filefield_paths in order to not lose support.

Will make a patch if I have a moment but wanted to get this bug known.
