2014.12.21 MSS Code Factory 2.1.12724 Beta 1

The rules and models have been refreshed, and a run of CFDbTest 2.2 produced
the code with no obvious errors.  It only took 4 minutes and 30 seconds to do so,
compared to the six hours plus that it used to take with 2.0.  So I didn't quite
get the 150 fold improvement I saw at first.

But to be fair, my poor laptop seems to be getting drive-IO bound.
