        - fixed hang we were seeing in Safari and layout tests

        * Misc.subproj/WebNSUserDefaultsExtras.m:
        (+[NSUserDefaults _webkit_ensureAndLockPreferredLanguageLock]): Change name to avoid conflict with Foundation
        function. This was causing the hang.
        (+[NSUserDefaults _webkit_defaultsDidChange]): Update caller.
        (+[NSUserDefaults _webkit_preferredLanguageCode]): Ditto.

        * WebCoreSupport.subproj/WebGraphicsBridge.m: Remove some unneeded includes.
