More continuous integration

Just to let you know that the continuous integration of Modules now covers the Windows OS. More precisely the Cygwin and MSYS2 platforms on Windows.

This addition completes the panel of OSes already tested after OS X and Linux (with multiple distributions tested for this one: Ubuntu, CentOS and openSUSE).

Each continuous integration job currently runs over 6k non-regression tests. And multiple CI jobs are affected to each OS to cover the different set of build option.

It would also be interesting to test against a native Windows installation of Modules. However specific build and install scripts have to be developed first to install Modules from its sources on a Windows native environment. (as always pull requests are welcomed)

I am also looking for an open service where some BSD OSes is available to also extend the CI to this kind of OSes. I would be glad to hear if something like that exist somewhere.
