[PySide] Fixing examples qt resource files under Python 3

[Roman Lacko]

Hi,

Here is simple helper script to regenarate recursively all existing qt
resource files in examples folder distributed in official pyside packages
built with pyside-setup.

It will be included in next release but it could be usefull if someone has
problems running examples under Python 3, where by default the qt resource
files are generated for Python 2 only.

Just run the follwing script with Python where the PySide is installed:

$ python regenerate_examples_qt_resources.py

Regards
-Roman
