Ogre3D / Okra Update

Okra (Common Lisp bindings for the Ogre3D engine) hasn't seen a lot of work lately. It covers my current needs and I've mostly been off to other projects. However, there's good news from the Ogre camp: there's now a community effort to create a C API!

I can only hope the API will have settled down before I return to using Ogre.
