Changes for 3.1.4

• Fixed Diagram.moveParts not to allow Link.invalidateRoute to recompute routes of Links whose Nodes are shifted by different distances when Link.adjusting is not None.
• Fixed LinkReshapingTool when handling multiple points in an orthogonal line. Also changed the z-ordering of reshape handles so that the end/outer handles are behind middle/inner handles, so that the ultimate handle is not in front of the penultimate handle.
• Fixed Panel.findObject so that it is no longer affected by whether there is an Panel.itemTemplate or template map.
• Fixed an inconsistency when querying the bounds of invisible GraphObjects (eg GraphObject.getDocumentBounds).
