Start work on new Loudness effect

This is based on my old loudness effect prototype which was included
in the Normalize effect.

Create all source files and add them to all build systems.
Currently, the effect only consists of a GUI mockup.
Create Octave+mod-script-pipe based dummy unit-test as well.
