Make modern versions of our old backup/load scripts.

The DB backup/load scripts are still around, but don't cover all models.
It's worth fixing up, since they can be useful when moving from sqlite
to something else.

They've been moved to be management commands now. This will be made
available to 1.6.
Did some sample backups and loads of my DB. I think it got everything.
