another round of small platform, libwnck patches

Hi,

Another round of small fixes.  With these I'm able to really
get my keywise hack going!  I finally found how to detect which
menu-item to bind the shortcut to: it's the one that has state
'prelight.  Please pull from urls below.  Hope I didn't miss a 
module.


Implement gtk-widget-get-state, makes reading of widget state
possible.
