Improved night sky v1.1

This mod improves the texture of the night sky and the moon, increasing it several times (128x128,
512x512 → 512x512, 1024x1024).

Fixes in 1.1:

- "The bright part of the Moon is slightly larger than the dark one." - corrected;
- Found a bug - "colorful" night - fixed.

Installation:
- Open x64a.rpf/textures with OpenIV (preferably the latest version);
- Replace the skydome.ytd file.
