TweakTool-3.18

Hi Gerald, this is probably gone now that you have gotten 3.18.x or still a
problem?

What you were supposed to have there is a on/off slider (see the attachment).

The code for powerbutton handling is now removed upstream.

I also booted and checked my Leap laptop, and there I have both still, so this
was possibly something that got fix'ed in the 3.16.x cycle, or your laptop's
lid is not recognized, and hence you are not shown the button for it.
