Pioneers Additions 1.3.3-1.21.4

Renamed "Ghost" group to "Gray" group
- "Ghosts" didn't really fit since the whole point is that players don't go into spectator mode
- "Gray" is more inline with the other color groups
Items rarities
- Miserable Obsidian remains COMMON (no change there)
- Holy Gold Ingot and Holy Diamond are UNCOMMON
- Lively Obsidian is RARE
- Life Token is EPIC
- These rarities come from vanilla Minecraft
- This is only really relevant to other mods that check for item rarities
Split config options into 2 tabs "Display" and "Functionality"
Lively Obsidian now glows similar to Crying Obsidian
