NumberFields@Home: GPU status update

It's been over a month since our last update, but I now have some good news. I have made some improvements to the GPU code and am ready to start deploying the new GPU apps.

I will start with the AMD OpenCL version for Linux. This will be a beta version. I have had a hell of a time with the AMD implementation of openCL, and this app still doesn't work on my Fedora system, and I believe strongly it's due to the graphics driver. But I have had the help of a volunteer named Wiktor and it runs fine for him (I believe he runs Ubuntu). Please keep in mind that AMD officially only supports RHEL and Ubuntu, so I will be interested to hear if this app works for anyone with an "unsupported" linux distro like myself.

I also have openCL Windows apps that were cross compiled using mingW. I have no means of testing these, so I am not ready to deploy them just yet. But if anyone would like to take them for a spin offline, please let me know, and I can send them to you.
