fix saving in adblock widget
Review Request #102362 - Created Aug. 18, 2011 and submitted
saving in adblock widget did not work because save() never got called. this patch fixes saving. i did post it here on reviewboard, because i think, there are other things that became obsololet when the adblock widget was moved out of the config dialog (the changed() signal for instance) and i could integrate them in one patch.
compiles and works.
