[Chameleon] Script called when hovering over any chameleon element for detailed online help

Carlo, the problem is that the images trap onmouseover events to  
handle the various button states.  What might be a useful extension  
to chameleon would be for button-based widgets to support attributes  
for mouseover and mouseout.  The function calls could then be  
integrated into the regular processing of the image swapping code and  
everything would work normally.  I don't really see a reliable way to  
fix this without extending the chameleon core code though.

All the modifications for this could be made to Button.php and  
cwc_button.js.  If you attempt it and it works, please consider  
contributing it.
