Moved AMOEBA include files to plugins/amoeba/openmmapi/include/openmm to be consistent w/ outlay other plugins, ...

Refactored ForceImpl, lots of KernelImpl subclasses, and other related classes to avoid redundant calculations when requesting a State with both forces and energies

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.

Downgraded recent cmake changes to ghastly compliance with cmake 2.4, for the benefit of the simtk dart server.

Modified Cuda FreeEnergy plugin to use a different windows export macro than main openmm library and cuda library.
Modified CUDA_NVCC_FLAGS to be consistent with Peter's latest version in all three locations they are defined.
Added "-Xcompiler '/MD'" to CUDA_NVCC_FLAGS on Windows to avoid link error in Cuda FreeEnergy plugin.

Export CudaFreeEnergyKernelFactory symbols to avoid link error in test program.

Still doesn't build on windows, but might help with linux (todo next)

Cast exponent in pow() function to RealOpenMM, to avoid overload ambiguity error on Windows when RealOpenMM is defined as double.

Associated code will be removed once confirmed deletions do not break builds
