Load the ParticlesOCL.cl from memory, using the MSTRINGIFY macro, instead of loading it from disk.

Small cleanup of cmake build for NVIDIA and AMD OpenCL

For AMD Stream SDK use:
INCLUDE_DIRECTORIES( ${AMD_OPENCL_INCLUDES} )
LINK_LIBRARIES( ${CMAKE_ATISTREAMSDK_LIBPATH}/OpenCL.lib )

For NVIDIA CUDA SDK:
INCLUDE_DIRECTORIES( ${NVIDIA_OPENCL_INCLUDES} )
LINK_LIBRARIES( ${NVIDIA_OPENCL_LIBRARIES})
