avoid using gtk_main and use gtk_dialog_run instead.

2005-08-06  Diego Gonzalez <diego@pemas.net>

	* gnome-about-me-password.c (gnome_about_me_password): avoid using
	  gtk_main and use gtk_dialog_run instead.
	  (passdlg_button_clicked_cb): rename to passdlg_process_response
	  (spawn_passwd): return a value, so that we can see if we need to
	  exit without using gtk_main_quit
	  (wait_child) avoid use of gtk_main_quit. More work is required on
	  this case, but for now it will be enough.

	Fixes bugs 312580 and 309736.
