Subject: image_buttons

Ignore-this: 418dbf488435c7c803695407557eecfb

* Added a XMonad.Util.Image module to manipulate simple images
  and show them into an X drawable
* Added the possibility of using image buttons instead of plain
  text buttons into the title bar
* Added a XMonad.Layout.ImageButtonDecoration as an example of
  how to use the image buttons
