I have a use case where I want to customize the JSON encoding of some
values to output to the template layer. It looks like
`django.utils.html.json_script` is a good utility for that, however the
JSON encoder is hardcoded to `DjangoJSONEncoder`. I think it would be nice
to be able to pass a custom encoder class.

By the way, `django.utils.html.json_script` is not documented (only its
template filter counterpart is), would it be a good thing to add to the
docs?
