BUG: Fix Unset test on VS 6 Visual Studio 6 does not recognize .cc as a C++ extension by default. Simplify the test to be C-only and use a .c extension.

ENH: Add unset() command. This introduces the unset() command to make it easy to unset CMake variables, environment variables, and CMake cache variables. Previously it was not even possible to unset ENV or CACHE variables (as in completely remove them). Changes based on patch from Philip Lowman. See issue #7507.
