[Javascript] Auto deleselecting a check box

   This is especially good advice if your "webmaster" is doing layout/content and then hands you a 
clunky HTML picture and asks you to make it 'work'  (then decides to again change the layout)

   The onClick method does not fire if you (gasp) use the keyboard.  If the object preceeding this 
control in the tabbing order was some kind of text entry, then the onChange method might be 
advisable - if a checkbox is clicked: it implicitly changes the value.  If there is no change upon 
moving through the control with Tab, then there's nothing to do anyway.  Whichever method is used, 
I agree that the state of the control's "checked" property should be considered if only for 'best 
practice' defensive coding.
