Fixing the CanAdjustLayout Ommision from CDockablePane

I work on an industrial HPC project that can run on either the CPU or the GPU. I usually use which ever one has the most horsepower on a given machine. It's written with CUDA with very few ifdefs used. My company is quite large, in the top five in our industry in North America, and I work in a small group with just five programmers.
