Duplicate reorders properties and adds unneeded x/y properties

When duplicating an object, all the properties in the duplicated copy of the object will have their properties reordered. This interferes with whatever user logic the original object had its properties ordered.

The order seems to be consistent for the duplicated object, but it also does not seem to follow any logical ordering such as the documentation. 

In addition, the duplicated object will have a slight offset added by changing the x/y property.

If there is no x/y property already defined it will add them, however this is unnecessary for objects that define their horizontal and vertical orientation using properties like anchors.horizontalOffset and anchors.topMargin.

When you grab and move objects that use properties like anchors.horizontalOffset and anchors.topMargin, those property values are changed so there is no reason for duplicated objects to add x/y for those objects
