- Mesh upload support

- LLMesh asset decoding and encoding (inc. LLPhysicsConvex, LLSkin, LLSubMesh)
- Query inventory folder by type
- onSelectedObject event
- fetchInventoryItem command
- Fix packing/unpacking of object shape
- Time sync with SimulatorViewerTimeMessage
- Changed several classes to a .from style rather than setting up in the constructor (exception friendly)
- Whole bunch of other improvements
- Object building
