A couple of changes to the cmake build system.

First:  Added a DESTDIR option for package building.
Second:  Change the OpenCL setup.  On both linux and windows use CLRun.  I completely removed the option here.  If CLRun works on MacOSX this should be done there as well, and this change implemented in the scons build also.  Then we could remove the HAVE_OPENCL and the new USE_CLRUN definitions.  Then we will finally have the dynamic detection of opencl set up cross platform.
On a side note, it doesn't seem that the program loaded from TextureDecoder.cl compiles or runs.
