[PyQt] signal issue with qbuttongroup

[Di Zou]

I switched to:

def AddApplication(self, id):
    print "hi", id

I also removed this:

addAppButtonGroup.setId(addCustomAppButton, 0)
addAppButtonGroup.setId(addAppleStoreAppButton, 1)
addAppButtonGroup.setId(addWebLinkButton, 2)

and it still doesn't work.
