Copied Visual Studio 2012 templates and adapted them for Visual Studio 2013

As discussed in #2754, this is a copy of the Visual Studio 2012 templates with the version number changed.

This should solve issue #2228.
Sorry, I was dazed. I was sort of getting at: What about people who are just running 2012? Are we copying their templates in too?
I assume these are still copied in somewhere else? (I don't know how the installer works)
