Factor out some stuff in their own functions.

Sun Apr 17 00:20:41 2005  Soeren Sandmann  <sandmann@redhat.com>

        * sysprof.c (on_open_clicked): Factor out some stuff in their own
        functions.

        * sysprof.c (load_file): Idle handler to load files given on the
        command line.

        * sysprof.c (main): If a filename is passed on the command line,
        load it in an idle handler.
