Unexpected data grid messages

[Pete]

Hi Keith,
I agree it would be nice to link dg's to their template in both
directions(there is a property of the dg that points to its template but not
the other way round).  Unfortunately, it's not quite as simple as it seems
since it's possible to have multiple dg's reference the same template (as
long as the format is the same of course).

I believe there is a message that happens when a dg is created (don;t
remember it's name) so it should be possible to write a handler for it to,
for example, set a custom property of the template card to the longd or ids
of the dg it references.  Come to think of it, I might look into that
further.
