2.2

Keeps the ramping limits working with VIEW firmware 1.8.56.

Works with VIEW firmware 1.8.54+; get 1.8.56 (naixx/VIEW)
for much lower CPU load and battery drain while shooting, and the new Cable Release mode on the VIEW.

Fixed

• Ramping options of a running time-lapse with VIEW firmware 1.8.56: the ISO, aperture and shutter limits
  take the camera's value lists from the settings message. Firmware 1.8.56 no longer repeats those lists in the
  status it sends on every frame (1.8 KB instead of 17 KB), so with ViewApp 2.1 the limits had nothing to pick
  from. Older firmware keeps working as before.
