[PyQt] override className() in QMetaClass

[Daniel Goertzen]

Thank you Rafeal, I forgot about that usage of metaclasses.  It certainly
cleans things up for me.  One thing of note is that the metaclass of QWidget
is not 'type', but 'pyqtWrapperType'.  So the invocation should be...

pyqtWrapperType(name, (gui.QWidget,),{'spam':spam, 'yam': yam})

... or more generically....

gui.QWidget.__class__(name, (gui.QWidget,),{'spam':spam, 'yam': yam})


Thanks again,
Dan.
