Organic: fixed tooltips for knobs that do not need a unit

For some knobs it doesn't make sense to use a percentage sign as unit.

Thanks to Tobiasz Karoń for pointing out this issue.
More artwork updates. New LCD numbers, triple osc artwork, lots of icons, some colour changes.
More new icons, triple osc artwork, scrollbars, etc.
Instrument: also render sound for MIDI-based instruments when muted

In order to provide smooth muting functionality (i.e. immediate proper
sound when unmuting) always render audio buffers for MIDI-based
instruments. This is more important than potentially reduced CPU usage
while muted.

Closes #69.

Lots of UI stuff again
UI: increased font sizes

As texts were not readable on high resolution screens the font size for
many widgets has been changed.

Closes #82.
InstrumentTrack: shorter label for FX channel spinbox
InstrumentSoundShapingView: shorter label for filter frequency knob
LedCheckBox: fixed label alignment

After switching to wide rectangular LED pixmaps and increasing the font
size we need to adjust aligment of label.
Timeline: use right click + shift to move left loop point

Moving the left loop point is now possible using right click + shift
instead of the middle mouse button (which is difficult on laptops).

Furthermore some coding style improvements.

Closes #81.
