Afterburner

Afterburner 0.2.0. One version number for every build now. What a build contains depends on its Minecraft version.

**Changed**
- Far terrain (where the build has it) starts off: switch it on in Options > Video Settings > Afterburner. Far terrain saved by earlier versions is ignored, and a chunk copied before its light was worked out is no longer saved (that caused gray boxes and black wedges at the horizon).
- Page links, icon, license and third-party notices are in the jar.

**Fixed**
- Forge: a rare server crash while generating new terrain (`featureList is null`): Afterburner asks again, and falls back to one thread if a parallel step fails. (Forge only.)
- Mixin config minimum version declared.
- NeoForge: the settings also open from the Config button in the mod list and with the `]` key, for packs where another mod replaces the video settings screen.
- Far terrain: a damaged saved file can no longer allocate a huge buffer.
