-Add Simon Detheridge's name to the About Box. --Bug fixes -Fix bug in OpenCL atomic string, which is never used. -Wrong hist and accum allocation size in RendererCL when using float-only buffers now. -Move some kernel initialization to a place where it's done once per render, rather than on every interactive iter chunk. --Code changes -Make ConvertCarToRas() just assign to the member rather than return a struct. -Make kernel string accessor functions in IterOpenCLKernelCreator, FinalAccumOpenCLKernelCreator and DEOpenCLKernelCreator be const and return a const string reference. -Don't include atomic string unless locking on the GPU, which is never.
