New foobar2000 grouping scheme

Just made this:

$ifgreater($strstr(%path%,'://'),1,radio,$if($meta(album artist),%album artist% - %album%,$if2(%album%,$directory(%path%))[ - '['%date%']']))

It basically bypasses fb2k's %album artist% fallback handling (because it sucks).
And uses directory name if no album artist is present and just shows "radio" for streams you might happen to have in a playlist (I got a separate radio playlist).
