input[type=hidden] should be display:none !important in the UA stylesheet

Reviewed by Tim Nguyen.
The HTML Rendering specification [1] renders hidden inputs with an
!important UA declaration:
input[type=hidden i] { display: none !important; }
WebKit's rule omitted !important, so a normal-importance author rule such
as `input { display: block }` (or a `display`-setting CSS reset) would win
the cascade and reveal hidden inputs, diverging from the spec and from
other browsers.
Add !important to match the specification and other browsers.
