LED control version ${status.version}

This toggle button is a stylised checkbox. data-bind="status.led1" binds it to the device variable. data-autosave="1" makes it send POST /api/status {"led1": VALUE} to the device every time the user toggles the button. On the device side, sync_status() is called every time the LED state is read or written.
