Added a button to remove a bookmark. (remove_bookmark_button_clicked_cb):

2003-10-14  Federico Mena Quintero  <federico@ximian.com>

	* gtkfilechooserimpldefault.c (create_shortcuts_tree): Added a
	button to remove a bookmark.
	(remove_bookmark_button_clicked_cb): New callback.
	(shortcuts_append_bookmarks): Show/hide the bookmarks buttons
	here, rather than in create_shortcuts_tree().
	(shortcuts_append_path): Return whether the operation succeeded.
	(shortcuts_selection_changed): Set the sensitivity of the button
	used to remove a bookmark.
	(shortcuts_append_bookmarks): Do not select the shortcuts folder
	here; let the caller do it if needed.
	(create_shortcuts_tree): Select the shortcuts folder here.
	(bookmarks_changed_cb): Likewise.
	(create_shortcuts_tree): Also set the sensitivity of the bookmarks
	buttons.
	(bookmarks_check_add_sensitivity): Renamed from
	check_bookmarks_sensitivity().
	(shortcuts_select_folder): Renamed from select_shortcuts_folder().
	(bookmarks_check_add_sensitivity): The current_path may not be set
	yet.
	(shortcuts_append_bookmarks): Oops, remove all the bookmark rows,
	not just the separator node.
	(bookmarks_changed_cb): Set the sensitivity of the bookmarks
	buttons.
