Cheng Zhao da3d4c8408 Allow renderer to get object in browser for arbitrary times.
Now, when creating a remote object in renderer, the browser will
reference the corresponding object by storing it in a strong map. And
when the remote object in renderer is GCed, the corresponding object
will be dereferenced in browser.
