Fixed bug with setting a style property to a unknown value in IE8 and lower
Merge branch 'supports' of https://github.com/Modernizr/Modernizr into supports
Updated comment re. try..catch in testProps
Changed nativeTestProps to only support a single value (no prefixing) and caveated a test which is only relevant when native detection *not* supported
