#21 Reliable backward compatability for barcodes

[Mike Knowles]

As the backgrounds and such are separated into
classes, each class should reset the random seed into
some munge of the main seed. If each class used a
slightly different seed built from the primary seed/code,
then each class could have its own random numbers,
and additionally would only have to be consistant with
itself in usage of that code. If several background items
were added there'd be no way for that to screw up the
compatability with race generation, and if more racial
info was added (say, age) it couldn't goof up stat
generation, and so on.
