qmidiarp 0.6.4 maintenance release

This is a one-year round-up release of qmidiarp. A few new little features have sneaked in and a few bugs have been fixed, both thanks to people filing tickets!
Nothing else to say, except that the detailed changes are right below:

qmidiarp-0.6.4 (2016-11-01)

Improvements
o All Modules now have the Note Filter already present in the Arps.
Also, the note range entries can now be set by MIDI learn
o Arp: The octave mode is now defined by independent upper/lower bounds
(feature request #12 by ssj71)
o LFO: New waveform flip button (feature request #11 by MilkMiruku)
o Seq: The output MIDI channel is now a MIDI controllable item. This
allows for instance an LFO to control the Seq MIDI channels for
dispatching sounds within a sequence (feature request #13 by Menno)

Fixed Bugs
o LFO: Offset slider didn't follow drawing and led to jumps on
first use
o LFO: Waveform type switched to custom when muting points (bug #16
reported by MilkMiruku)
o Arp: When using Global Storage "Restore", the restore step was
incorrect
