Added optional out attribute to packedItems node in polybuild to specify packed path.
Removed out attribute in favor of source attribute; this insures the path attribute in runinfo.polyrun will always reflect packed path.
Fixed entry point being packed twice.
2d physics entity scale is now forced to be positive to avoid issues with negative scale in box2d
