Building gtkmm-3.0 with Visual Studio 2013

* You will need Visual Studio 2013 (MSVC 12.0). Earlier versions of the compiler, including 11.0 and earlier will not work.
* Install the latest Win32 GTK+ Development files from ftp://ftp.gnome.org/pub/GNOME/binaries/win32/gtk+
* Build libsigc++, glibmm, cairomm and pangomm from source.
* Add GTK+, libsigc++, glibmm, cairomm and pangomm to the include and lib paths in Visual Studio, if they are not in
  $(srcroot)\..\vs12\$(platform)
* Load the MSVC_Net2013/gtkmm.sln solution.
* Build the entire solution.
* Run the tests.
