Fix scaling in IE10 docked window mode

[grockett]

IE10 zooms the page out when docked window mode is used, making most sites unreadable. A CSS property tells it not to.

Thanks. I prefer not to include code targeting unreleased browsers. IE10 is still some way off and these sorts of things in an unreleased browser are better dealt with by reporting it to the IE team as an issue.

Furthermore, using device-width (in the HTML) isn't a magic bullet, so I'd be very reluctant to include it in the CSS without some pretty rigorous cross-browser (inc. mobile) testing.

I'm going to close this for now; hopefully it is addressed in some form before IE10 is out. If not, it can be reassessed at that time.
