Note-compiler is _mostly_ complete; plus some tiny bugfixes

The note-compiler can read a program-definition and emits a cpp-file
which implements that definition. This implementation is optimized.
HOWEVER, the compiler still does not emit a set_param() function. this
will lead to a linker error because the function is not implemented
(but defined). After adding an empty implementation by hand the emitted
compiles well, and also seems to work when used in the synth.

TODO:
 - implement set_param()
 - compiler must emit a loader-function (which returns a new Note)
 - use that loader function in the synth
