huge change on project layout.

The intention is to have PySide2 and Shiboken2 as project names, to
allow for co-existence of PySide and PySide2.

This is the first version that builds with these settings on OS X:

    $ python3 setup.py build --debug --no-examples --ignore-git --qmake=/usr/local/Cellar/qt5/5.5.0/bin/qmake --jobs=9

This is not yet tested.
