Fixed the Stage Editor bug that for rendering

After the code was refactored, many of the "urls.py" files had been
changed, resulting in the removal of /client.js from the files referenced.
However, /stage/editor.html had relied on an old function from /client.js,
json_request, to make requests, resulting in bugs that prevented
rendering. Since this was the only function referenced from /client.js,
and the remainder of the file was old code from the warmup login project,
I opted to move the function into /stage/editor.html instead of adding
/client.js to the relevant urls.py files again.
