--User changes

-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.
