    NMake Makefiles: Use toolset version in DLL/.lib naming
    
    Instead of using the Visual Studio version ('vc150' for Visual Studio 2017),
    use the toolset version ('vc141' for Visual Studio 2017 and 'vc142' for Visual
    Studio 2019, as defined by Microsoft) so that we are more in-line with what
    is now done in the pangomm-2-42 branch.
    
    If using the old naming convention is desired, an NMake command line option
    'USE_COMPAT_LIBS' have been added-note that this will require glibmm, cairomm,
    and libsigc++ to be built with that option enabled.
