    Update README.txt for MSVC Builds
    
    Tell people that they need to download and install the Adwaita icon theme,
    by following the instructions given on
    https://live.gnome.org/GTK%2B/Win32/MSVCCompilationOfGTKStack.
    
    Also tell people they can either use IJG JPEG or libjpeg-turbo for non-GDI+
    builds of GDK-Pixbuf.
