	Fixes for bugs 690 and 733, to make the clipboard
	work for file editing in place, and make sensitivity
	work. Paste doesn't work correctly still, and a bug
	is filed for this issue.

	* libnautilus-extensions/nautilus-entry.h:
	* libnautilus-extensions/nautilus-entry.c:
	(nautilus_entry_initialize_class), (nautilus_entry_key_press),
	(nautilus_entry_motion_notify), (nautilus_entry_set_text),
	(nautilus_entry_set_selection), (nautilus_entry_insert_text),
	(nautilus_entry_delete_text):
	Added a new signal to nautilus entry, called "selection_changed"
	that is fired whenever the region selected in an editiable widget
	is changed.  This is used to determine how to set clipboard sensitivity
	correctly.

	* libnautilus-extensions/nautilus-icon-container.h:
	* libnautilus-extensions/nautilus-icon-container.c:
	(nautilus_icon_container_initialize_class),
	(nautilus_icon_container_start_renaming_selected_item),
	(hide_rename_widget):
	Add a new signal "renaming_icon", which tells the icon view
	to set up clipboard capabilities for the new editable widget

	* libnautilus-extensions/nautilus-icon-private.h:
	* libnautilus-extensions/nautilus-icon-text-item.h:
	* libnautilus-extensions/nautilus-icon-text-item.c:
	(iti_stop_editing), (iti_entry_text_changed_by_clipboard),
	(iti_start_editing), (iti_destroy), (iti_start_selecting),
	(iti_stop_selecting), (iti_event),
	(nautilus_icon_text_item_get_renaming_editable):

	Sad hacks that I had to add on top of this already scary file so
	that the editable, which is in its own offscreen window somewhere,
	communicates to the clipboard what is actually going on when text
	is entered and selections are changed.  This includes adding a
	new signal when text is changed, to make sure the entry knows about
	it, firing an initial grab focus for the widget so that the widget
	turns on, passing on more of the events of the canvas
	widget, including motion notifies and focus events, and
	keeping a persistent copy of the last renaming entry in the icon
	container so that pastes for that widget will still work.

	* libnautilus/nautilus-clipboard.h:
	* libnautilus/nautilus-clipboard.c: (set_menu_item_sensitive),
	(set_paste_sensitive_if_clipboard_contains_data),
	(set_clipboard_menu_items_sensitive),
	(set_clipboard_menu_items_insensitive),
	(clipboard_items_are_merged_in),
	(set_clipboard_items_are_merged_in),
	(merge_in_clipboard_menu_items), (merge_out_clipboard_menu_items),
	(focus_changed_callback), (grab_focus_callback),
	(selection_changed_callback),
	(initialize_clipboard_component_with_callback_data),
	(nautilus_clipboard_set_up_editable),
	(widget_was_set_up_with_selection_sensitivity),
	(first_focus_callback),
	(nautilus_clipboard_set_up_editable_in_control):
	Reorganized some of the code, and also added new callbacks
	to deal with sensitivity changes.

	* src/file-manager/fm-directory-view.h:
	* src/file-manager/fm-directory-view.c:
	(fm_directory_view_get_bonobo_control):
	Add a new function that the icon view uses to
	pass the bonobo control for clipboard set up

	* src/file-manager/fm-icon-view.c: (renaming_icon_callback),
	(create_icon_container):
	Set up clipboard capabilities when the renaming widget is
	created.

	* src/nautilus-location-bar.c: (nautilus_location_bar_new):
	* components/notes/nautilus-notes.c: (make_notes_view):
	* src/nautilus-simple-search-bar.c:
	(nautilus_simple_search_bar_new):
	Changed calls to clipboard set up routines to include
	the new shares_selection_changes parameter. Widgets that
	use the "selection_changed" signal (NautilusEntries)
	say "TRUE" here, otherwise selection doesn't work quite
	right, and FALSE is used instead.

	* src/nautilus-search-bar-criterion.c: (get_size_location_for):
	Deal with the case when a user has entered a non-numeric size
	in a smart way, by using nautilus_str_to_int.  This is related
	to bug 2438, but is not a complete fix.
