RogueCraft Infinite Dungeon Crawler

Fixed a couple glitches with the Nether

Fixed the glitches with Seals

Touched up some of the rooms, removed errant items and blocks

One last loot table fix (fishing)

Achievements now all work correctly and prerequisites apply universally

Ghosts of monsters no longer appear in the safe room during maze generation

Removed Herobrine

Banged my head and eventually gave up trying to find a workaround for MC-82703 which causes:

 - Invisible chests

 - Mystery Mob Spawner particles

 - Brewstands with enchanting books above them

 - Mob Spawners that don't show what they spawn
