- Add "GET" method to Caps

- New events: ObjectPhysicsDataEvent, ParcelPropertiesEvent, NewObjectEvent, ObjectUpdateEvent, ObjectKilledEvent
- Added getXML function to Color4, Vector2, Vector3, Vector4, GameObject, Region, Quaternion, UUID for opensim-compatible XML export
- Added TextureAnim and ParticleSystem decoding to the "full" ObjectStore
- Object store will automatically request missing "parent" prims
- "setPersist" - When persist is TRUE, the ObjectStore will not forget about "killed" prims - useful for region scanning
- Support for Flexible params, Light params, LightImage params, Mesh data, Sculpt maps
- Fixed object scale being incorrectly calculated
- Add terrain decoding (this was a ballache)
- Add parcel map decoding
- Add support for region windlight settings (region.environment)
- Add support for materials (normal / specular maps)
- Add getBuffer, getLong and bitwiseOr to UUID
- Added a circular-reference-safe JSONStringify to Utils
- Add XferFile capability to Circuit

PUBLIC API:

- NEW: getMaterials() - resolves material UUIDs

RegionCommands:
- NEW: getTerrainTextures()
- NEW: exportSettings() - OpenSim XML export of region settings
- NEW: async getTerrain() - Get binary terrain heightmap, 256x256 float32
- resolveObjects() - now fetches task inventory contents too.
- resolveObjects() - fix calculation of land impact
- NEW: getObjectByLocalID(localID: number, timeout: number)
- NEW: getObjectByUUID(uuid: UUID, timeout: number)
- NEW: getParcels();
- NEW: pruneObjects - removes missing GameObjects from a list
