use same keys/behavior as in icon view). There are a few
	minor bugs remaining that I'll write up separately.

	* libnautilus/nautilus-list.c:
	NautilusListDetails struct: added fields for
	keyboard_row_to_reveal and keyboard_row_reveal_timer_id;
	(nautilus_list_initialize_class): Removed key binding set for
	this class (uses key_press_event function instead); used
	gtk_binding_entry_clear to get rid of all the unwanted GtkCList
	key bindings; wire up key_press_event function; wire up
	destroy function
	(nautilus_list_destroy): New function, destroy details struct
	(this was storage leak) and clean up pending timer.
	(nautilus_list_clear_keyboard_focus), (nautilus_list_set_keyboard_focus),
	(nautilus_list_keyboard_move_to), (keyboard_row_reveal_timeout_callback),
	(unschedule_keyboard_row_reveal), (schedule_keyboard_row_reveal),
	(reveal_row), (nautilus_list_keyboard_navigation_key_press),
	(nautilus_list_keyboard_home), (nautilus_list_keyboard_end),
	(nautilus_list_keyboard_up), (nautilus_list_keyboard_down),
	(nautilus_list_keyboard_page_up), (nautilus_list_keyboard_page_down),
	(nautilus_list_keyboard_space), (nautilus_list_activate_selected_items),
	(nautilus_list_get_first_selected_row),
	(nautilus_list_get_last_selected_row),
	(nautilus_list_key_press): New functions, all the mechanism for
	handling key presses similarly to NautilusIconContainer. Bonus
	key handling for Page Up and Page Down.
	(nautilus_list_move_focus_row), (scroll_vertical): Removed these
	functions that were used by the GtkCList key bindings in favor of
	nautilus_list_key_press and friends.
