Checkpoint lwcc development
Changed tactics with the preprocessor. Instead of getting clever and trying
to do things the "fast" way, instead, just tokenize the whole input and
process it that way. Also, set up so the preprocessor and compiler can be
integrated instead of having to have a specifically correct output for the
preprocessed file.
Also removed the subdirectories in the lwcc directory. It made things more
complicated than they needed to be.
