A userscript to simplify and beautify the NASA Astronomy Picture Of the Day website.

• Removes excess content.
• Adds a dark background.
• Oversized previous and next links.

2023-10 v6:

• better handling of credits (that may be sometimes "credits and copyright")

2023-10 v5:

• added credits

2023-10 v4:

• adapted to recent changes in the web page that made the image invisible (should be compatible with previous pages though)
