need change log events for attributes and types assigned to groups when they are deleted

There arent any change log events on group.delete() for types (and maybe attributes). Here is the cause:

Hib3GroupDao:

// delete attributes
ByHql byHql = hibernateSession.byHql();
byHql.createQuery("delete from Attribute where group_id = :group");
byHql.setString("group", _g.getUuid() );
byHql.executeUpdate();
// delete type tuples
byHql = hibernateSession.byHql();
byHql.createQuery("delete from GroupTypeTuple where group_uuid = :group");
byHql.setString("group", _g.getUuid() );
byHql.executeUpdate();

Here is a potential solution from Peter DiCamillo (though we probably just want to select the objects and call .delete() on them so they are processed normally with hooks etc:
