noexcept support in Visual Studio 2015

[j-o]

Since Visual Studio 2015 supports the noexcept specifier, the definition of the NOEXCEPT macro should be adjusted accordingly (# if defined(_MSC_VER) && _MSC_VER < 1900) or removed entirely, as it is not actually used anywhere. Same goes for all cmake-init based libraries.

NOEXCEPT in fact isn't used in our public libraries but in our internal ones that are build upon cmake-init, too.

This will be covered while porting the project structure to cmake-init 2.0.
