Typo - Missing quote mark in docs in rev/models/querysets

[y_feldblum]

Apologies for a nitpick so seemingly minor, but we all start somewhere. :P

I apologize, but I was not sure how to give a more precise description of where exactly the typo was, such as line number. I was also not sure how to give a patch for documentation items.

The typo is about a sixth of the way down the page, where there is a missing single-quote-mark. The text in question is:

[{'blog_id: 1, 'headline': u'First Entry', ...}, ...]
