Visual Studio C++ Windows Forms Designer Support

Added support to maintain designer functionality for Visual Studio C++
Windows Forms projects.  Also added a test project showing how to use
the CMakeLists.txt file and, when successfully configured, will allow
use of the designer for the included form.

The changes primarily revolved around tracking .resx files and applying a few extra tags inside the Visual Studio project and filters files.  I also used a few of the existing project variables to help.
