COMP: Superbuild - Now downloading PythonQt from http://github.com/commontk/PythonQt

That new repository contains two branches:
 - the default one named "patched"
 - an other one named "svn-mirror" which is used
to track the official repository of PythonQt

Since the patched are kept in a separate branch, that will make easier:
1) merge of the official mirror with our patched version easier
2) eventual contribution back to the upstream svn easier
