Note: MorphWithGrid does not really make sense unless you have a
superclass MorphWithDnD (Drag and Drop) which handles the morph droped
and makes them 'sticky'.

Though refactoring PastUpMorph by inserting superclasses is an issue I
suggest to put this on the backburner at the moment and focus on
getting the Etoys setting straight as Dave suggests in the initial
mail.

A use case to follow: What happens when you drop  the exapme project

    http://etoys.laptop.org/src/Content/ExampleEtoys/CarAndPen.014.pr

on to the desktop.

ExternalDropHandler>>handleDroppedItem:event:  [21]

is called in this case and then dispatches to do the necessary things
to deal with the
    ExampleEtoys/CarAndPen.014.pr
file.

There is a message box which needs attention.

And I assume that in the course of these events some settings are
necessary. Most prominently to choose EtoysProject and no longer
MorphicProject
