** Fix for bug #219197

	** Fix for bug #219197

	* e-shell.h:
	* e-shell.c: (e_shell_can_quit), (e_shell_do_quit), (e_shell_quit):
	Call of e_shell_quit divided into two functions, one to check if quit
	is acceptable by all components and second to do quit.
	* main.c: (gnome_master_client_save_yourself_cb),
	(gnome_master_client_die_cb), (main):
	Quit application when session dies.
