Add get_tcp_stream_count() to the TCP dissector and modify graph_segment_list_get() to allow matching based solely on a stream. Use text instead of icons for the mouse click behavior buttons. Remove their PNG resources since we aren't using them any more. Fix setting the cursor in the graph widget. svn path=/trunk/; revision=51989
