Feat/planbuild support and 1.6.1 release

[zolantris]

In 1.6.0+ this mod supports PlanBuild a popular blueprinting mod.

Support is added via a patch that makes PlanBuild use the Raft localPosition instead of world position which each item
could be moving/swaying and updating as the PlanBuild iterated through the items. This easily breaks the Plan save.

• Hopefully this logic can be incorporated within PlanBuild directly. There is a config toggle to turn this patch off to
  future proof things.
• Alternative approaches for this could be doing a detection if the game object is attached to a parent object and
  calculating coordinates of the items after all object positions have been fetched.
