OpenCL: Moved the OpenCL code from the compiled source to a separate file TextureDecoder.cl and added a .rules files to copy the updated version to the build directory. 

Fixed RGB5A3 decoding with alpha
New CMPR decoding, blocks with no alpha are great, still have to figure the problems with transparent blocks. Disabled for now.
Added a better error reporting to the base OpenCL functions
