GLTF Import - Metadata support #184

Limited support of metadata import is added to RWGltf_GltfJsonParser. Following Json data types are currently supported: int32, double, string, array of int32, array of double, array of strings, Json object. Notable unsupported types are: binary data, array of Json objects. Metadata is processed for nodes and meshes. Tests "gltf_export" are updated with import testing and renamed to "gltf". Method RWGltf_GltfJsonParser::gltfParseSceneNode() is slightly refactored: parsing of transformations and transformation matrices is moved into separate functions.
