* Added Unity 2018.3 and Later + 2019.x support for the new Prefab system. * Changed to version dependent code to remove deprecated warnings in Unity 2018.3 and later. * Moved asset to Plugins/Imphenzia folder to follow asset best practices. * Changed namespace to Imphenzia.SpaceForUnity to avoid naming conflicts. * Removed SU_ prefix from all scripts as the new namespace takes care of conflict avoidance. * Included a check and option to automatically change the settings for the Main Camera to set proper Culling and Depth when creating a Space Scene. * Included the option to change from the default layer 20 to another layer for the Deep Space layer. This includes setting the layer to the custom layer for all the instantiated space scene objects. * Added automatic check to name the Deep Space layer to �DeepSpace� when starting the SPACE for Unity editor window. * Modified the Static Stars to use a larger custom skybox that also remains stationary to replicate the behavior of the nebulas and galaxies. The custom spacebox will be slightly larger than the sphere of nebulas. * Changed the size of the space sphere (nebulas and galaxies) to 8.5 times the original size. This makes it easier to see the space scene in the scene view and it also allows for more movement within the space scene’ before exiting a boundary. * Change the Far Distance of the Space Camera to 100000 to accommodate the enlarged Space Sphere and Static Stars. * Renamed the editor window and script to SPACE for Unity (instead of Space Scene Construction Kit). * Changed particles to default particles for Space Particles. * Changed materials for Space Particles and Space Fog to new shader (instead of legacy shaders). * Updated documentation.
