* https://discourse.libsdl.org/t/sdl-moving-to-github/28700 announced
SDL's move to GitHub. While I'm sad they give more power to GitHub,
I'm happy I can include SDL as a submodule
* Change register -> def in order to match other functions
* Removed extra BuildDependencies.sh because it's no longer needed!
* Build_Debug.sh will now build Cakelisp itself, keeping it up-to-date
in case you update or are iterating on it
* Update Cakelisp for run-process-sequential-or and comptime function
fix (building build-ogre and build-sdl is how the bug emerged)
* Ogre and Ogre's dependencies now built via run-process functions
* Updated Ogre because I thought it might have issues (I caused the
issues). It's good to be more up-to-date anyways
* Removed extra BuildDependencies.sh because it's no longer needed!

* Update Cakelisp for run-process-sequential-or and comptime function
fix (building build-ogre and build-sdl is how the bug emerged)
* Ogre and Ogre's dependencies now built via run-process functions
* Building each app separately was causing rebuilds of comptime
definitions, which I have now fixed in Cakelisp
* Moved some SDL stuff around and added a initialize function which
should support using SDL for drawing
