swh plugins:  Fix SWH destructors

The constructors had been fixed with commit #83c2019, but I had missed
the destructors.  This corrects the `_fini()` destructors as well.

PianoRoll: CSS stylability
Most parts of piano roll are now stylable:
- background color
- note color
- bar color (for volume bars)
- grid color
AutomationEditor: improve zoom functionality
- entire wheelevent code was written very... weirdly, I simplified it
- fix bug with x zoom with mousewheel, no more getting stuck between 25/50
- ctrl+shift+mousewheel now zooms y-axis
- ctrl+alt+mousewheel now changes quantization
AutomationEditor: CSS stylability
AutomationEditor - fix previous
PianoRoll: wheelevent improvements, similar to AutomationEditor
- ctrl+alt+wheel changes q (as in auto)
- ctrl+shift+wheel changes note length
- changed note lock functionality slightly, it no longer changes itself to 1/16 because this would cause annoying infinite scrolling with the wheel, instead it just acts like 1/16 when notelength is last note
