    MSVC 201x builds: Allow different Python versions per toolset
    
    Use conditionals to select the Python installation, so that we can more
    stick to the default Visual Studio versions used to compile each
    official Python releases more closely.
    
    This means by default:
    -2010/2012/2013 builds use Python 3.4.x, which is built with 2010
    -2015/2017 builds use Python 3.6.x, which is built with 2015
