Don't include the examples in the install or egg.

Add a bogus Extension object so setuptools will know that there are binary extensions and will use the platform and architecture in the egg file name.
Use my repos for pyside and shiboken submodules
Add a release-with-debug-info (relwithdebinfo) build mode, which will build normal release mode binaries, but will also include the *.pdb files in the install or egg, to facilitate debugging on Windows without needing a full debug build.
Add a '1.1.2en' release tag which will include Enthought modifications.
