	Ported GimpNavigationView to use actions for its buttons:

	* app/menus/menus.c (menus_init): register a <GimpNaviagaionEditor>
	UI manager containing the "view" action group.

	* app/actions/actions.c (action_data_get_foo): handle "data" being
	a GimpNavigationEditor.

	* app/actions/view-actions.c (view_actions): added tooltips for
	the actions used in the editor.

	(view_actions_update): use action_data_get_display() instead of
	checking the type of "data" manually.

	* app/widgets/gimpeditor.c (gimp_editor_add_action_button): use
	a GtkToggleButton instead of GimpButton for GtkToggleActions.

	* app/display/gimpnavigationeditor.[ch]: added a GimpMenuFactory
	parameter to the public constructor and removed all other
	parameters. Simplified gimp_navigation_editor_new_private() and
	use gimp_editor_add_action_button() instead of just add_button()
	for creating the buttons. Made gimp_navigation_view_set_shell()
	private. Update the UI manager when the shell zooms or scrolls.

	* app/dialogs/dialogs-constructors.c (dialogs_navigation_view_new):
	pass the menu_factory to gimp_navigation_editor_new().

	Removed #includes which are not needed any more.
