Fixing MFC compile errors in Visual Studio 2013

If you get the error:

Error 1 error MSB8031: Building an MFC project for a non-Unicode character set is deprecated. You must change the project property to Unicode or download an additional library. See http://go.microsoft.com/fwlink/p/?LinkId=286820 for more information. C:\Program Files (x86)\MSBuild\Microsoft.Cpp\v4.0\V120\Microsoft.CppBuild.targets 376

It can be fixed by installing the Multibyte MFC Library for Visual Studio 2013 which can be found here.
