Names Changed

[bastiaanzapf]

Hey Joe, i changed the function names according to your suggestion, and I found a solution for the "Filter-inside-a-filter"-problem, namely, implementing the Filter ad-hoc (which isn't too hard with a leaky integrator).

There's still a few issues, especially with the triangular-wave generator, which are "fixed" for now (at least inaudible, if not understood and controlled) - but this is something for the future.

Cheers Bastiaan. As there's quite a lot here I'll pull it into a review branch and have a proper look when I have a moment - probably next week some time.
