Add initial code for the note-compiler

The note-compiler now has a Parser class which knows about possible
parameter changes (by controller, velocity or simply user definition).
Furthermore, several files were adapted (by stripping unneeded code,
adding the bool foo_const variables etc.).

Small fix in util.c which causes extract_var("foo") to return "foo"
instead of "".

Fixes in both Makefiles.
