TBOSS 2.0: Turing, chained progressions, presets' own chord sets, the editor's tabs, MPE

TBOSS 2.0, with 1.8 and 1.9 (which were not released on their own). Install it from the browser:
https://armandhammer.github.io/TBOSS/install.html (Chrome or Edge; click Save settings first to keep your settings).

New in 2.0 (manual)

• Turing pattern for the arpeggiator: a random loop of the held notes that changes a little each time round.
• Chained progressions (P1 > P1 > P2 …) and each chord's chance of resting or playing the borrowed chord.
• Presets with their own chord sets, colors and curves; Clear preset on the board.
• U3 as Shift, and Shift + the buttons under the screen on every screen.
• Sleep and Shut down.
• The step sequencer: Fill steps, nudge, each lane's swing and transpose, Mutate and Stutter.
• Spread of Bass, and the Settings menu rebalanced into 17 pages.
• The web editor has its own USB port (TheoryBoard Editor), so your DAW keeps playing while it is connected.
  Leave that port off in the DAW. The editor follows changes made on the board.

New in 1.9 (manual): the board set up from the web
editor: every setting, seven color schemes, velocity and pressure curves drawn with the mouse and a calibration, the
step lanes as a grid, the chord pads' edits, presets named, copied and compared.

New in 1.8 (manual): MPE, Glide, Vel full with the
Firmer and Firmest curves, and play/stop on the step screen.

Tested on one board with Ableton Live. Settings → About shows 2.0; the web editor's header shows the build, 2.0.8.
