Update (package.json) -> Better JSHint checks

Linters should be blunt and opionated. Make JSHint complain more.
Add (ie10-fix.js) -> IE10 media query fix

Internet Explorer 10 doesn't differentiate device width from viewport
width, and thus doesn't properly apply the media queries in CSS.
Normally you'd just add a quick snippet of CSS to fix this:

@-ms-viewport{width:device-width;}

However, this doesn't work for devices running Windows Phone 8 versions
older than Update 3 (a.k.a. GDR3), as it causes such devices to show a
mostly desktop view instead of narrow "phone" view.

Thanks twitter bootstrap!
