* idl/nautilus.idl (ViewWindow): Added `application' readonly
	attribute.
	(Application): Renamed attribute from `windows' to `view_windows'
	and made it a sequence<ViewWindow> rather than
	sequence<Object>. Renamed `new_window' method to
	`new_view_window'.
	* src/ntl-window.h: Miscellaneous reformatting.
	(nautilus_window_close): Added prototype
	* src/ntl-window.c: Added implementations of
	Nautilus::ViewWindow's methods. For now, _get_application just
	returns CORBA_OBJECT_NIL because the Application object has not
	yet been implemented.
	(nautilus_window_close): New function used by `file_menu_close_cb'
	and `impl_POA_Nautilus_ViewWindow_close'.
	(would_be_in_gdk_pixbuf_if_federico_wasnt_stubborn_pixbuf_render):
	Added an explanatory comment.
