Activity Feed

OK, the bottom of the homepage now has an activity feed. It displays your friends' recent forum posts, group forum posts, debate comments, debate judgments, and profile status updates.

Problems:
> It looks kinda ugly. I'm still thinking about how to make it more attractive. Maybe I should get rid of one of the boxes (I'm thinking "Recent Debates") and slot this in there instead?
> Is there anything else you want this to display?

Incidentally, here's a quick video about my background and my goals for edeb8. It's displayed on the homepage for non-logged-in users.

Just improved this by removing all duplicates from the feed.

admin: Cool!
