Cascade Deletions

[Cam: @muunkky]

Hi there,

For basic CRUD operations Rise automatically generates Delete methods
for each entity. However, in order to delete dependent objects I have
to create a composite method to cascade those deletions. Usually I use
the ON DELETE CASCADE constraint on the relationships so deletions
automatically cascade as desired.

If I could alter the deletion cascade behaviour property of
relationships, this would be a useful addition.

Best Regards,
