LibGUI: More work on GCheckBox.

- Make it track the mouse cursor just like GButton does so that changes only
  get committed if the mouseup event happens while inside the widget rect.

- Draw a focus rect around the box when appropriate.

- When focused, support toggling the checked state with the space bar.
