    @short      factory to create handler-objects
    @descr      These class can be used to create new handler for specified contents.
                We use cached values of our configuration to lay down, which handler match
                a given URL or handlername. (use service TypeDetection to do that)
                With a detected type name you can search a registered handler and create it with these factory.
