Do dependency reordering for dump-out

[tbk303]

The dump-out command takes a list of tables that are
exported in that sequence. It would be nice however if
the sequence would be re-ordered before export so
that dependencies are minimized.
This allows to dump-in the tables without having to
drop constraints.
Ok, this cannot help for cyclic dependencies
(which still requires switching off constraints for the
import) but for many schemas this would help definitly.
