Show binary sensors in Home Assistant's words and grey out what is off (0.2.62)

A binary sensor's tile and card now say what Home Assistant says for its
device class, such as Open or Closed for a door and Wet or Dry for a leak
sensor. The screen maps the class it already receives, with the same words
as the top bar and the history card; a test keeps both tables equal. A
history card still waiting for its answer no longer shows the previous
card's word.

Lights and binary sensors that are off turn grey, as in Home Assistant, and
a light without an icon of its own shows a crossed-out bulb while it is off,
on the tile and in the top bar. A chosen icon stays and turns grey.
