They don't do anything useful yet.

	* libnautilus-extensions/nautilus-program-chooser.h,
	* libnautilus-extensions/nautilus-program-chooser.c:
	New files with code for creating a program-choosing
	dialog (which is really degenerate right now).

	* libnautilus-extensions/nautilus-program-choosing.h,
	* libnautilus-extensions/nautilus-program-choosing.c:
	New files with functions for choosing a component or other
	program to display or open a file with. This uses the
	dialog in nautilus-program-chooser, but callers don't
	need to know that.

	* libnautilus-extensions/Makefile.am: add these new
	files to the build.

	* src/file-manager/fm-directory-view.c:
	(fm_directory_view_chose_application_callback),
	(fm_directory_view_chose_component_callback), (choose_application),
	(choose_component), (bonobo_menu_other_program_callback),
	(other_application_callback), (other_viewer_callback):
	New functions that connect the program-choosing UI to the
	menu items.
	(compute_menu_item_info): Stop desensitizing the "Other ..." items.
	(append_gtk_menu_item): Eliminated this function, made callers use
	more elaborate append_gtk_menu_item_with_view instead.
	(fm_directory_view_real_create_background_context_menu_items),
	(create_open_with_gtk_menu):
	Updated callers to append_gtk_menu_item.
	(fm_directory_view_real_create_selection_context_menu_items):
	Pass view to create_open_with_gtk_menu.
	(reset_bonobo_open_with_menu): Now takes an FMDirectoryView and
	uses it as callback data for "Other..." items.
	(fm_directory_view_real_merge_menus),
	(fm_directory_view_real_update_menus): Pass view to
	reset_bonobo_open_with_menu.

	* src/ntl-index-panel.c: (command_button_callback): Renamed from
	command_button_cb, also broke out application-launching code and
	moved it to libnautilus-extensions/nautilus-program-choosing.c.
	(nautilus_index_panel_chose_application_callback),
	(open_with_callback): New functions, used to wire up functionality
	of "Open with ..." button.
	(add_command_buttons): Stop desensitizing "Open with ..." button,
	and wire it up to do something.

	* src/ntl-window.h: Renamed field "option_cvtype" to "view_as_option_menu".
	* src/ntl-window.c:
	(nautilus_window_constructed): Updated to match field name change.
	(nautilus_window_switch_views): New function, broken out of
	view_menu_switch_views_callback; switches window to new content view.
	(view_menu_switch_views_callback): Now calls nautilus_window_switch_views.
	(synch_view_as_menu): New function, resets displayed name of "View as"
	menu to match current content view.
	(chose_component_callback), (view_menu_choose_view_callback): New
	functions, used to implement "View as ..." menu item.
	(nautilus_window_load_content_view_menu): Store iid in menu item;
	call synch_view_as_menu; wire up "View as ..." menu item.


	* src/ntl-window-msgs.c: (handle_unreadable_location):
	Tweaked wording of an error message.

	* src/file-manager/fm-error-reporting.c:
	(fm_report_error_renaming_file): Tweaked wording of an error message.
