Client: Remove Parameters's dependency on remaining Applet APIs

The only place that uses the applet is TellFriendHandler and the method
it calls opens a pop-up and accepts any Java AWT component. Therefore,
it is safe to rename to applet field in Parameters is to rootComponent
to remove the coupling from the deprecated Applet class.
