This was causing issues with our ability to unsubscribe from
streams with " in their names.
The solution here is a bit hacky, since it depends on the JavaScript
being fairly aware of the layout of the DOM, which is not great.
But it works.
This fixes Trac #328.

Rather than calling the template generating code once per
subscription, let's just do it in a batch when possible.
With about 100 subscriptions, the "fetch" call takes about 800ms to
render (while testing locally) both before and after this change,
which is somewhat disappointing.
But this *is* cleaner!

In particular:
* Taking a list of streams as arguments.
* Using the _backend model so that we can have an API version.
* Considering "not subscribed" to be a non-fatal error.
And of course the corresponding changes to subs.js.
