Update on Power PC OSX support

We have been going through various shortages for Power PC OSX WUs, due to the new cores not supporting PPC machines.  While we expect that we may have new PPC WUs in the future, we want to give a heads up that we are depreciating PPC OSX support in Folding@home.  We would love to support as many OS's as possible, but the overall compute power from the PPC group is small enough, and the efforts to support it large enough, that we have decided that it is better for us to put our resources into improving support for the other OS's we are supporting.   

Thanks to all of you who have faithfully supported FAH with the processing that you have donated!
