I changed the download callback function to take both the current file
and the entire list xfered/totals, which gets rid of that done parameter
and cleans up the code a bit. Graphical clients could probably use both
since it's easier to draw two progress bars in a GUI.
I haven't tested this code as much as my other patch so watch out for
any bugs.
