Fixed shiboken for Linux and py3k. In separate recipe, because I had to change a lot.
Small fix in shiboken recipe. Note that is deprecated anyway
as far as Pyzo is concerned (see next commit).
Adding recipe that can build PySide on Linux with py33

Builds shiboken, pyside and pyside-tools all in one go.
Needs support for OS X.
Also, needs patching RPATH to make it work. I thought Conda
would do that for me...
