Ptevent Drupal being broken in Internet Explorer 8+

Under certain circumstances (eg intranet sites), IE8+ falls into "compatibility" mode. This breaks all kinds of CSS (eg menu bar) and makes it right impossible to use some JS stuff:

The fix is to include
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
right after the tag in html.tpl.php.
If it's inserted later, it might not work.
