Moved OpenSim/Framework/Communications/Capabilities up to OpenSim/Framework/Capabilities. Didn't change the namespace because VC# is not helping, and this would imply manually changing more than 50 files. So the namespace is still OpenSim.Framework.Communications.Capabilities, to be cleaned up later by someone with more energy.
