Marked as WIP since this will use the lock button from !425 (closed) and i don't want to interfere with @julian.sparber 's work there.
This is on top of !432 (merged).
TODOs:
-
Once !432 (merged) is in i can use that to hook up the rotation toggle. -
rotate built-in not primary display -
unclaim sensor on screen blank not screen lock
Closes: #18 (closed), #56 (closed), #540 (closed)
