support css value !important

$('div').css('blue', '!important');

That example doesn't even make sense, there is no property named blue. That probably would have been a bit more obvious if the PR had added unit tests. See #1385 for a previous failed attempt, and check out our Contributing site for more help.

I guess the OP meant:

$('div').css('color', 'blue !important');

That said, the PR introduces the nativeCSSStyleDeclaration support test but doesn't use it and doesn't test it (see test/unit/support.js; btw, I don't think the support test is needed on master) and, as @dmethvin pointed out, there are no unit tests attached.

Also, this is a pretty critical code path and the !important use case is not terribly common; I'd like to see perf tests to make sure it doesn't make it worse for the 90% use cases.

Thank you for taking the time to submit a PR, but this will not make it in.
