Halting work on preprocesser units and rewrite as a whole

I've decided to split the project into 2 repositories: the assembler
and the runtime.  The runtime will contain both the executable and
lib/ while the assembler will have the runtime as a git submodule and
use it to build.  I think this is a clean solution, a lot cleaner than
having them all in one project where the Makefile has to massively
expand.
