Moved Meta Viewport from global head.tpl to diabook's header

I mistakenly added this <meta> tag to the global header, but it
causes problems for other themes, as they have other optimal widths.

I also added a style to diabook which makes the jGrowl messages
appear below the header bar, so you can still click the menu items
without having to close messages first.
