Title: Fix #posts not being cleared.

Uses this technique: http://www.quirksmode.org/css/clearing.html

Without it, anything under #posts div will get messed up because parts of the last .post will float into them.
This effectively adds a div style="clear:both" under #posts, but without changing the markup.
