[Bug 977189] Add product/topic to question listing

This adds the product and topic that a question was asked under to the question listing, and also puts a little itty bitty logo next to it. The logos are mostly useful for Firefox and Thunderbird, but sort of suck for anything else. The words link to a filtered version of the page with those things searched for. (Clicking on the product filters by that product and any topic, clicking on the topic filters by the product and the topic).

@rlr brainstormed a few ideas for how to make those icons look better and/or be more useful, but nothing really sounded exciting enough to implement, so I didn't. I also played with generating appropriately sized images to try and make things better (manually and automatically). It didn't make them prettier, so I left it out. The good news is, this will look better on retina automatically (yay).

r?
