* 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
