pianoroll improvements:

- add label / activeLabel controls
- add new pianoroll options:
  - fill
  - fillActive
  - strokeActive
  - stroke
  - hideInactive
  - colorizeInactive
  - fontFamily
- add wordfall method
- fix: some haps were drawn with wrong length
- pianoroll labels now use set fontFamily
- hide fold gutter
