Title: Moog ladder filter

This is a digital approximation of the famous Moog Ladder filter.
It is based on the work of Antti Houvilainen.
Code fragments found at: http://musicdsp.org/showArchiveComment.php?ArchiveID=196

It has a double steep 24dB/Okt roll-off compared to the "Filter effect"
The resonance can be cranked up to self resonance, which produce a prominent sweeping effect.

IMHO this is a nice addition to MIxxx and a good counterpart to the subtle "Filter effect" pull request, which is included in this PR as well.

Both are designed to be an EQ replacement if desired.
