Eternity Enchantment

Black Sun - Ninefold Starry Sky: fixed "cannot be summoned at all in some modpacks"

• Symptoms before: the Eclipse Sigil did nothing on right click, the spawn egg did nothing, and /summon only said the entity could not be summoned. The problem happened at the moment the entity was created; it is fixed now.
• The Eclipse Sigil now also works while aiming at a block (previously only when aiming at air). New command: /eternity blacksun (summons in front of you).
• A failed summon now states the reason in chat instead of staying silent; if another mod blocks it, it is undone for you and retried on the next tick.
• Fixed: the Seraph form used to heal back to full when the world was reloaded.
