Rite of Returning 1.0.82

Changes:
- Confirmed the mod contains no Iron's Spells / irons_spellbooks mana references.
- Undead-host players wearing any helmet no longer burn from fire/daylight ticks.
- Symbiote owners now keep 5 absorption hearts, regenerating 1 heart every 60 seconds if missing.
- Symbiote owners gain +20 natural armor and +3 attack damage.
- Symbiote owners attacked by entities enter aggressive defense mode.
- Aggressive defense attacks nearby mobs every 15 seconds with only 2 tentacles.
- Added keybind 6: Symbiote Climbing.
- Symbiote Climbing sends 5 tentacles to nearby blocks within 15 blocks.
- Symbiote Climbing grants slow creative-style flight while tethered.
- If the player moves beyond 15 blocks from the anchor, climbing releases and the player falls.
- If the tether stretches past 10 blocks, the symbiote tries to reattach to a closer block.
