Experimenting with IE support

<!--[if IE 8]><meta http-equiv="X-UA-Compatible" content="IE=7"/><![endif]-->
<!--[if gt IE 8]><meta http-equiv="X-UA-Compatible" content="IE=edge"/><![endif]-->

    I've been experimenting with this in a couple of projects.
    
    For animations, IE8 compat mode is noticeably quicker/smoother than
    IE8 strict. Since I still give 'full' support to IE7 (barring the
    odd text-shadow etc which IE8 doesn't support anyway) I use the tags
    above to push IE8 into compat mode for smoother animations, but allow
    the much faster IE9 to try its standardsy best.
