Describe the bug
The moon appears as a transparent overlay on top of the sun, it should block the sun completely.

Also, the dark part of the moon is visible in the day. So crescent moons in the day look full.

To Reproduce
For eclipse:

• Disable the daylight cycle
• Set time to noon
• Run /time add 5d a few times until the moon is near the sun
• Use /time add to increase time incrementally to have the moon overlap with the sun
  For crescent:
• Add a few days do the previous state of the lunar cycle to have the moon in a crescent (or other) phase in daytime.

Eclipses not working isn't a bug per se, it just wasn't ever implemented. All the planets are transparent. Even the sun is transparent. The stars. They must be for them to disappear into the sky (if i recall what i was told, anyway)

As enhancement, duplicate of #29.
