 Make playlist table header menu, (See Play _streamTableHeaderContextMenu).
-Make PlaylistEntry numbers use NSNumber.
-Instead of LengthString, use a formatter.
 
-Add automatic header seperator without testing explicit types. Pull out binding? Perhaps the table column can do a objectAtIndex and then get a stringValue to get the width.
