        This behavior was introduced in bug 8223 to match IE and Firefox. But it doesn't appear that we're matching
        any browser today, and CSSOM spec agrees with them.

        * WebCore.exp.in: Don't export CSSStyleDeclaration::setProperty(), no one is using it.

        * bindings/js/JSCSSStyleDeclarationCustom.cpp: (WebCore::JSCSSStyleDeclaration::putDelegate): Use regular
        setProperty(), not the incorrect version that's being removed. Properties set via IDL attributes are never
        important.

        * bindings/v8/custom/V8CSSStyleDeclarationCustom.cpp: (WebCore::V8CSSStyleDeclaration::namedPropertySetter):
        Made the same fix for v8. Why did v8 bindings authors copy/paste the code?!

        * css/CSSStyleDeclaration.cpp:
        * css/CSSStyleDeclaration.h:
        Removed a version of setProperty() that attempted to parse the value and extract !important from it.

        * html/ImageDocument.cpp:
        (WebCore::ImageDocument::resizeImageToFit):
        (WebCore::ImageDocument::restoreImageSize):
        (WebCore::ImageDocument::windowSizeChanged):
        * page/DragController.cpp:
        (WebCore::DragController::concludeEditDrag):
        We never needed to use this version of setProperty() here, it was just unnecessarily slower.
