Removed ALREADY_MODIFIED_PATH variable in gpu sniffer link stanza, which I am pretty sure would not have worked as desired.

Modified link path in platforms/cuda/CMakeLists.txt to increase likelihood that CUDA_HAVE_GPU flag will be set.

Including installing Test<Platform>HarmonicBondForce tests.

Added modern findpackagehandlestandardargs technique to FindCUDA.cmake, to permit configuration on machine
with no cuda installed.

Changed link line for gpu sniffing program so it works on Windows with new single FindCuda location.

FindCUDA.cmake.

based on the FindCUDA.cmake that was in the platforms/cuda/cuda-make directory.
Setting of CUDA_NVCC_FLAGS is now in top-level CMakeLists.txt, in case I ever figure out how
to get this working with the cmake 2.8 installed system version of FindCUDA.cmake.
Before this change, there were three separate FindCUDA.cmake areas.  Now there is just one.
