If you try to read a save file back into a Torque database you might
notice that every object will get a new primary key value, even if you
saved these values into the save file. This is fatal if you want to
keep your foreign key relations and even more fatal if you need
integrity of your save files.

This patch allows a restore program to use Persistent.save(true)
and friends to skip the idbroker. The normal methods work as before.

This patch needs rebuilding of your OM scheme.
