* Added specialization of DatabaseMapper, DataReader and ObjectFieldMapper to support LLVector3, LLQuaternion and LLUUID

* Added PrimitiveBaseShapeTableMapper to show how it's done

NOTE: Nothing actually works yet - this code should be considered more of educational value until it's all wired together
