HUGE thanks to Noobly Walker who practically carried most this update

Added:

• Added a bunch of famous moons and some dwarf planets (don't question how you're able to see them with just a spyglass)
• Added star spectral classes - Stars are now divided into distinct spectral classes (O, B, A, F, G, K, M) which dictate their size and brightness and are by default distributed based on real life (most stars are M-class), the distribution can be made uniform in the config
• Added multiple meteor shower colors
• Added a bunch of config settings for how stars appear

Changes:

• Stars now lose brightness with distance, giving a more 3D feel to the Milky Way galaxy
• Minimal distance at which Z sky axis is rotated by 90 degrees has been changed from 100 000 blocks to 10 000 blocks
• Year length is now configurable

Fixes:

• The Moon's phases should now properly line up with where it is in the sky
