          Restore color profile after a crash

        * DumpRenderTree/DumpRenderTree.m:
        (crashHandler): Added a handler for signals that are raised on a crash. Keeping separate
        from the existing handler for manual interruption (SIGINT/SIGHUP/SIGTERM), because
        I'm trying to find a way to prevent the Crash Reporter dialog from appearing on crash,
        and this code may change significantly.

        (main): Install crashHandler.

        (setDefaultColorProfileToRGB): Properly convert CFStringRef to a char buffer
        (CFStringGetCStringPtr should NEVER EVER be used!).
