new release for 0.4.0

This new release contains some graphics updates, as well as a couple of new modules:

Evolution: a module based on my Turing patch, containing a shift register which is progressed on every trigger. The first entry is either taken from an existing (some steps down, determined by he length parameter), or with a given probability (REPLACE) from one of the inputs A or B. A more

BPM-tools: A beat per minute detector, which outputs 3 clock (same beat, and some multiple of it, including swing) as well as CV values to synchronise an Fundamental LFO , SEQ-3, or DELAY.

OctaFLop: a 8-fold flip-flop, which is internally wired to work as binary counter, if no further inputs are connected.

S&H 8: a simple set of 8 sample and hold modules.

A more detailled description of the modules will follow.
