Updated starmap demo code to reflect ccpwgl.js refactoring

Updated starmap code, fixing a bug introduced in `wrappedObject` refactoring, that was causing hundreds of pilots to fly straight into angry Goonswarm pilot gatecamps, due to malfunctioning navigational systems. It was kind of nice because i'm planning to start selling brand new ships. Anyway, navigational systems **should** work as intended after pull request merge.
