Twilight at Noon

First release.

Added

• Scenario engine with five presets (Distant Strike, Strategic Strike, Full Exchange, Already Winter, Endless Winter), shareable seed codes and three time scales. In singleplayer and on servers that have the mod it runs on the server for everybody; anywhere else it runs on your client.
• The strike: siren, streaking warhead, flash (double flash when Reduced Flashing is off), fireball, mushroom cloud, vapour dome, shock band and a blast that arrives after the real delay.
• Fallout and radiation sickness: ash, soot, embers, black rain, a dose model that follows the 7-10 decay rule and reacts to shelter, and sickness that grows with the dose.
• Items: Geiger Counter, Thermometer, Iodine Tablets, Canned Beans and a four-piece Hazmat suit with its own armour texture, all craftable.
• Mobs: the Ash Walker (hostile, carries radiation sickness) and the Scavenger (a wandering trader in a gas mask).
• Radiation effects: Radiation Sickness and Iodine Shield, a radiation damage type, a creative tab, spawn eggs.
• Server control: /nuclear start|jump|detonate|skip|stop|status|dose|cure for operators and the twilightRadiationDamage and twilightRadiationSpeed game rules.
• Nuclear winter: soot veil, dimmed daylight (block light is untouched), smoke-coloured sky, closing fog, and grass, leaves and water that fade to ash grey and ice blue.
• Snow cover: the whole land turns white as the winter gets colder, rooftops and treetops included, without changing any block.
• Cold world that works without a scenario: blizzards, visible breath, frost on the screen, thermometer with wind chill.
• More than two dozen synthesised sounds.
• Full settings hub in Mod Menu, the /twilight command and a keybind (K) for Scenario Control. The dosimeter and thermometer can be tied to the items.
• Reduced Flashing on by default, camera shake option, shader safe mode and performance presets.
