Practice widget

I'm submitting this so you can take a look. There's no link anywhere, you get to the widget by going to either question/some_id/answer or project/some_id/answer. (just add /answer to the end of some question or project show page)

It is assumed that some other site will record information, so there's very little security on this widget (for example you could mess with the url's).

If you see anything that needs to be done, please tell me.
