- Improve the SCsub to allow unbundling and remove unnecessary code.
- Move files around to match upstream source.
- Re-sync with upstream commit 308db73d0b3c2d1870cd3e465eaa283692a4cf23
  to ensure we don't have local modifications.
- Doesn't actually build against current version 5.0.1 due to the lack
  of the new ArmaturePopulate API that Gordon authored. We'll have to
  wait for a public release with that API (5.1?) to enable unbundling.
