        Bug 10632: Objective-C DOM should use the @property syntax for DOM attributes
        http://bugzilla.opendarwin.org/show_bug.cgi?id=10632

        Generate @property when MACOSX_DEPLOYMENT_TARGET is >= 10.5.
        This is backwards compatible with the getter/setter methods.
        Generate setter arguments with a "new" prefix to avoid the property
        name conflict warning. Also removes some whitespace and the comments
        that we added to the headers. This makes the headers look like what we ship now.

        * bindings/objc/DOMCSS.mm:
        (-[DOMDocument getComputedStyle::]): renamed a local variable to avoid the property name conflict.
        (-[DOMDocument getMatchedCSSRules::]): ditto.
        * bindings/scripts/CodeGeneratorObjC.pm: generate @property in the headers.
