    README.win32: Mention about /utf-8 and GIT
    
    Let people know that Visual Studio 2015 and later provide a /utf-8
    option to eliminate the need to set the System's non-Unicode locale and
    the subsequent reboot.
    
    Also let people know that it is recommended to have GIT for Windows
    installed so that some dependencies' sources can be downloaded and built
    along with GLib et al when needed.
    
    Please see MR !65 for a discussion on the reasoning why GIT for Windows
    is recommended.
