libremetaverse/OpenMetaverse/ObjectManager.cs
John Hurliman 99239ebcfc * Splits libomv into OpenMetaverseTypes.dll and OpenMetaverse.dll 
* All MathUtils and non-SL-specific Helpers functions have been put in OpenMetaverseTypes.dll inside the Utils class. Helpers only contains SL-specific functions now
* LLSD encoding/decoding for custom types has been moved out of the types and implemented as static functions in the LLSD class
