Update README.md
Merge branch 'master' of github.com:maartenba/MvcSiteMapProvider
MVC 3 builds wouldn't compile on machines without Windows Update MS14-059 with the previous patch (84f43d2). This patch makes the build work whether or not the Windows Update is installed on the build machine, with the caveat that when the update is on the build machine, it must also be on the target machines as well. Otherwise, it the binaries will work in either environment.
