Adds the ability to save yourself from the darkness by holding an illuminating object in hand.
This is implemented by adding tags to items:
Items tagged with edl:safe give the Veiled effect when held in the hand. The effect disappears when in water. (Default: Torch, Soul Torch, Lava Bucket)
Items tagged with edl:water_safe give the Veiled effect when held in the hand even in water. (Default: Lantern, Soul Lantern, Glowstone Block, Sea Lantern, End Rod, Beacon)
