Added ground perspective and fixed stars

Added a feature where you can select a position on the earth and view from there. You do have to manually add your latitude and longitude but eventually you will be able to select from a map or search for a specific city. (The demo shows London UK’s position so I don’t reveal my own)

I also fixed the lag from the stars that was making the site slow, now it can display 3500 stars and all the other objects just fine.
