Title: overqualified h1

Removed h1 type selector prepended to the #header ID selector. This syntax is allowed by W3C standards (http://www.w3.org/TR/CSS2/selector.html), but it's considered by some to be inefficient practice: "If a rule has an ID selector as its key selector, don’t add the tag name to the rule. Since IDs are unique, adding a tag name would slow down the matching process needlessly." See https://developer.mozilla.org/en/Writing_Efficient_CSS. CSSLint (not something the MWF is following, and I'm not advocating it should) calls this sort of selector overqualified. Google also suggests removing overqualified selectors: http://code.google.com/speed/page-speed/docs/rendering.html
