Non-logged in comments

[richardtape]

At the moment, if the user isn't logged in, they can't comment. (actually there's a JS error, but that will be fixed in the next commit)

Allow for the user to enter their details. i.e. use the comment_form() function to produce the markup.

This will need to be a change upstream?

066686a stops the JS errors (and makes a 'default' dummy user. - this will be replaced in the future, but my current use-case is for sites with only logged in users. I promise I'll get to this...unless someone else wants to tackle it...)
