Major Update One! — Stellar Navigator Steam update #1502946

This major update brings with it several new features including multiple galaxies! New Feature: Import / Export of Galaxies Import / Export of Star Systems Import / Export bulk star systems from the galaxy map A "Navigate to" button within the star system catalog to focus and select planets Changes: The galaxy map now shows the name of the galaxy. Fixes: Fixed the overlap of orbital lines so they now always appear behind the planetary objects. Fixed the atmosphere artifacting over planets. This included a modification to the atmosphere shader which now also allows multiple light sources to cause the atmosphere to "flare up". Overall quality of the atmospheres should also be improved. Fixed the point light on secondary stars which prevented the light source from following the new star. Now planetary objects with stars on either side will receive light correctly.
