Simple switch for Natural Scrolling. (Reverse mousewheel or trackpad direction)

Registered by ianp5a

Add simple switch to reverse the mousewheel or trackpad scrolling direction like in Ubuntu Tweak and OSX Lion.
Reasons: To be compatible with Tablet touchscreens. As well as it is more logical. Up means Up.
Expectation: Push mousewheel or touchpad scroll up, and page in window moves up. Eg in a browser or Nautilus or anywhere with a scroll bar.
Switch to be in the most logical place for new users to find.
