v0.13.0

One feature, for the season it arrives in: a way to tell NeverDry that the
garden is resting for the winter, or that nobody is home to water by hand.

Added

• Away and off-season: an operating mode for each hub. A new selector on the
  hub's device page, Operating mode, tells NeverDry what you are doing. Away
  keeps the valves watering and stops the requests to water by hand, since
  nobody is home to act on them; warnings about the installation itself (a valve
  that does not close, a silent meter, a flat battery) still arrive. Stopped
  is for the off season: NeverDry sends no command to any valve, does not expect
  them to answer, and sends no notification at all, leak alarms included. The
  water balance keeps computing, a valve you open yourself is still recorded
  (but no longer closed for you), and the Irrigate buttons are refused with a
  message rather than saved for spring. Switching takes effect at once without
  reloading the integration, so a watering in progress is not cut short by
  going Away; going Stopped during a watering ends it and closes that
  valve. The mode applies to the whole hub for now: a greenhouse and an outdoor
  garden on the same hub share it until environments can be set independently.
