[PyQt] Help with help action

[Michael Towers]

Hi Thorsten,

You're not 'show'ing your help widget, which I imagine should be some 
sort of pop-up. For example, something like:

    def help(self):
        dlg=QtGui.QDialog()
        browser = QtGui.QTextBrowser()
        browser.append('Help')
        layout = QtGui.QVBoxLayout(dlg)
        layout.addWidget(browser)
        dlg.exec_()
