          NativeFileUpload: Button text is not grayed out when the control is disabled

        Covered by fast/forms/file-input-disabled.html 

        * css/html4.css: Changed selectors that had pseudo-classes after the -webkit-file-upload-button
        pseudo-element to have the pseudo-element at the end. Pseudo-elements must be at the end.
        * rendering/RenderFileUploadControl.cpp:
        (WebCore::RenderFileUploadControl::createButtonStyle): Changed to not overwrite the button's
        style with its parent's style. getPseudoStyle() handles inheritance properly.
