[plt-scheme] OSX drag-and-drop

You'll need to override the on-drop-file method of the frame.

To get the stuff dropped on the application to start it up, check in
current-command-line-arguments. 

After the app is started up, dropping something on the app in the
finder calls the on-drop-file method of the frontmost frame.
