made the projects (example + ofxKinectForWindows) fully VS2012

Not sure if you want to maintain this as a separate branch or not? I followed the instructions in the 2nd answer on this page to fix the projects (unloading, editing the xml, and reloading).

Hm you do seem right looking at the diff. That bit actually *I* didn't change, I just changed the project files not the solution. VS2012 makes those changes to the solution automatically when you open the solution in VS2012.
