Fix errors with invalid bone node path in Polygon2D 
NodePath properties are designed to be relative to the given node, so
validity checks are failing in the editor for Polygon2D nodes, which are
relative to the Skeleton2D node rather than the Polygon2D node.

Fixed by saving bone paths as String properties instead of NodePath.

Shouldn't cause a difference for performance since NodePath properties
are technically saved as String anyway.
