Subject: [PATCH] allows "deprecated" model metadata tag to exlude cars from
 being utilized for ordering, but will allow them to run out their lives on
 the rails until they export.  Useful for when you mod in a car, and want to
 remove it without hunting around to find all of them and deleting them.
