Remove underused json_respond

This should help resolve a circular import wherein "import jsonresponse"
triggers "from r2.lib.pages.things import wrap_links" in jsonresponse.py,
which triggers "from pages import *" in r2/lib/pages/__init__.py, which
further triggers "from r2.lib.jsonresponse import json_respond" in pages.py
