Avoid requesting unnecessary thread responses

This adds a simple mechanism to view any template file directly in a browser. The intention is that we can use this to build up reference HTML files which illustrate common UX patterns. We can then view the resulting pages without having to have a working implementation.

In development mode, the URL is /template followed by the path to the template file. For example, you can view the 404 page at:

    /template/404.html

You can also supply string parameters to the template by specifying them as query parameters in the URL.

e.g.  /template/my_template?name=Foo

screen readers. Also, the mathjax message should be wrapped to prevent
non-IE browsers from complaining about a feature that is IE-only.

The front-end code for rendering a thread always makes an AJAX request
for the resopnses, regardless of how the thread was accessed (directly
by URL or by selecting it from the thread list). Previously, when
a user accessed a thread directly by URL, the LMS would initially
request the thread from the comments service with responses, but that
response data was never actually used. Now, the responses are not
fetched with that initial query.
