BetterWeather: Renewed (Beta)

Fixes

Crash on world tick (#2). Fixed a NullPointerException while iterating loaded chunks for lightning — the chunk list is now snapshotted so spawning a bolt or probing neighbour chunks can no longer modify the map mid-iteration.
Clouds through underwater/world fog (#3). Clouds and weather no longer render through underwater and lava fog; the pass is skipped while the camera is submerged.
Rain colour toggle. "Beta 1.7.3" now applies a real blue rain tint vs a neutral modern tint, instead of a difference too small to notice.

New

Vanilla Rain Control. Optional mode that ties rain to the vanilla weather state, so /weather rain turns every cloud into a rain cloud globally instead of using localized fronts.
More in-game config. Vanilla Rain Control and Frequent Rain toggles, plus a Reset to Default button.
Higher cloud view distance. Now up to 64 tiles via a dynamic cloud pool, with an "expect heavy lag" warning past 16.
Documented commands. /findrain (locate the nearest rain front) and the debug commands are now in the README & Russian Language Translations
