Adding support for Visual Studio 2017 projects and solutions.

Does not add the VisualStudioVersion and MinimumVisualStudioVersion in solution
files, but VS2017 opens those fine regardless and picks them up first even when
VS2010, 2012, 2013 and VS2017 are installed as well.

Added corresponding tests and verified that all is as expected.
