Sprint 14 Complete

Sprint 14, which contained mainly render optimisations, is complete. Its difficult to hand-on-heart say its totally done but I'm content with the results for now. Vertex Transforms are down, the draw speed it way up, and I've added the first significant command line switches and config options - more will appear now the code to read them is in place.

There are a couple of bugs to wrap up the Pre-Prototype so sprint 15 will be a series of consolidation tasks before mainline features-first development continues. Signing off sprint 14 with a couple of known bugs feels pretty low, but they are the highest priority item in sprint 15 and I'll hit those first.

Other than ensuring stability, I haven't got much planned for sprint 15. There are some physics improvements to make so it'll be a good time to roll those in.
