Toggle Style Class on Mousemove

When the mouse moves while over the avatar then toggle the style class back and forth between the 'over' and 'not-over' style classes (defined in demos.css). The effect is to turn the border back and forth between dashed and solid.

$proto('#avatar', {
  Mousemove: {
    onMousemove: {
      ToggleClass: {
        styleClass: 'over',
        otherStyleClass: 'not-over'
      }
    }  
  }
});
