0.2.4 Moon rework.

It is now a sphere Previously it was a texture; no matter how much you scaled it up, it still looked like a sticker. Now it has a real spherical surface: light only illuminates the half facing the sun, and the terminator is a computed curve; the closer to the edge, the darker it gets; the side facing away from the light has earthshine reflected from Earth, so even the "new moon" shows its outline instead of being a black blob.

It also wobbles slightly (libration)—the lunar surface slowly moves relative to the terminator, which a flat texture cannot do.

Bigger and more complete Apparent diameter about 72°, about 81° at full moon (the vanilla moon's apparent diameter is 0.5°) The entire moon is basically in the sky, no longer having its lower half cut off by the arena edge When the field of view is widened, it grows accordingly, ensuring it is the same giant moon under any view settings Lunar surface Uses NASA's measured lunar surface data (LRO/LROC, public domain): craters, maria, and the rays of Tycho are all there.
