New look, new home page

Just pushed out a newly skinned site.  The layouts are a bit cleaner and nicer (and there's another Robot hiding in the footer!).  In the continuing search to surface the best projects and make them as easy as possible to find, we've also redesigned the home page a bit, including adding a Project of the Day.  There's also a note from the Editors, which we'll update frequently as updates occur!

Several bugfixes are out as well, most importantly the fixes for comments with images, and the Paypal button which sometimes was not pushable in Firefox.
