Add logout button to power-button long press menu
The menu that is toggled by long-pressing the power button or by clicking the power-button in the settings menu has shutdown but no "logout/switch-user". I wonder where we'd best place that as it's useful when phosh runs with a display manager (which is about always the case except currently on PureOS).
@snwh do you have an idea here? I was thinking that we could make the "power off" button in the above screenshot swipeable or long-pressable to switch function (it's not a frequently used feature or one that is absolutely necessary to operate the device).
