* develop:
  [AUTO] : updating submodule reference to latest autogenerated bindings
  closed #3463: Potential hash collision by using typeid(T).hash_code() in JSB and LuaBinding. Instead of using std::unordered_map<long, T>(long is the hash_code generated by typeid(T).hash_code()), We needs to use std::unordered_map<std::string, T> to avoid collision since unordered_map internally processes collisions.
