Remove Tracker's special DnD handling. Instead, BTextView/BTextControl now

honors drag messages containing entry refs and resolves the path of the first
one contained. Will work on a more sophisticated solution that would allow
optionally extracting the file text instead via right click drag context menu 
when I have more time.
