Initial Qt5 support.

- Clicking OK in dialog windows does not close them, only cancel does, was that already the case with Qt4?
- It does not complain that I have a version of CGAL that does not have a Qt5 component, so the tests are probably not sufficient. However, it still compiles, links and runs. What is the CGAL Qt component used for?
