Site redesign: header bar and new masthead for the homepage

This commit is a combination of Eli's new blue header bar (with some
height and color modifications) and Cole's new masthead. I tried to get
the masthead close to the spec, but that wasn't entirely possible. Fonts
weren't standard, for example.
