Any interest in adding comments?

[pmeenan]

It looks like it should be trivial to implement DISQUS to add commenting to the site (and to the tests themselves) but I wanted to gauge the level of interest before I looked into it too much.

This may be something that makes more sense for private installs vs. the public instance so various people can attach comments directly to a test result (and spam isn't as much of a concern).

Thoughts?
