OneDimension 1.0.1

A fixes release for hostile-mob spawning and per-band atmosphere.

Fixed

Hostile mobs now spawn properly. A bad monster-spawn light setting on the world type meant hostile mobs would only spawn in near-total darkness, so almost nothing spawned in the Overworld or Nether bands. Spawning now works normally — at night and in dark caves.
Endermen spawn in the End band again. Because the stacked End is lit by the sky (unlike the real End), the normal darkness rules kept endermen from spawning up there. The End band now uses the End's own spawn rules — endermen spawn anywhere that isn't lit by a torch, regardless of the time of day.
The End and Nether bands no longer darken at night. They share the Overworld's day/night clock, so setting the time used to dim the whole world. Both bands now keep their own constant lighting (matching the real Nether/End), so /time set night only affects the Overworld band.
End music now plays in the End band. It previously kept playing the Overworld track; you'll now hear the End theme up top. (Nether music already played from its biomes.)
