Subject: * Added ThirdParty node for external library sources that are shipped
 with the solution. * Added conceptual TribalMedia.Framework.Data library;
 this is meant as a generic database layer abstraction library, that should be
 specialized into OpenSim.Framework.Data * OpenSim.Framework.Data should
 subclass FieldMappers to extend LLVector3 and LLQuaternions
