Eidolon : Repraised

Fix music disc playing only for few seconds. [Emery]
Fix permanent ethereal hearts not generating without an external kickstarter, and reduced default maximum.
Fix rituals taking the focus item as simple pedestal item and invalidating the ritual midway. Fix few advancements not triggering.
Reworked angel sight ring to work while CoFH core is present. [coAuth: Siver]
Blacklist for enchantments that should not show in the soul enchanter [Siver]
Adds the ars ecclesia to the tags for bookshelves and lecterns.
Rework signs to work with mods like amendments.
Move athame foraging results to recipes.
Adds red candles to valid altar upgrades.
Adds rituals for Ravens and Slugs
Adds configs for the chants (pray cooldown, cost, etc.)
Adds optional mode (configs) for the Crucible that gives a bit more wiggle room to check the recipe between each step, the crucible will keep waiting with a looping timer instead of just failing after the first timer expires.
NOTE: this is experimental and doesn't mean that you can start the step and adjust your inventory midway, it will probably have more iterations before becoming the default.

The scriptorium is basically not implemented yet, for those wondering. No ETA for backports atm.
