I just committed a small fix because the space event was not swallowed, 
causing the html view to scroll when you pressed space on a focused label.

Also fixed a small problem with checkboxes (and radio) that where checked 
twice on keyboard when pressing space on them.

The patch is trivial, so i just committed. Regards
