Bunch of Modded Hearts + Book of Virtues Support

[ryondinkus]

Accidentally did all this shit in one branch so this is really big.

MODDED HEARTS

• Immortal Hearts: Add a new Heart fly type called Immortal Heart Fly. Spawns two on heart pickup. At the end of the room, if you have an odd amount of Immortal Heart Flies, you gain an extra one.
• Moonlight Hearts: Added Moonlight Heart Flies. When collided with bullet, will reveal a part of the map, open a red room, or grant a tears up. Gain 1 fly per heart.
• Patched Hearts: On pickup, will remove the appropriate amount of Broken Flies. If you have no Broken Flies, grants the appropriate amount of Red Flies instead. Comes in single and double. Gain 2 flies per heart, or 4 for double.
• Web Hearts: Added Web Heart Flies.When collided with bullet, spawns a few Blue Spiders. Also grants slowing effect to enemies on collision. Comes in single and double. Gain 1 fly per heart, or 2 for double.
• TODO: The 17 hearts from REP+ when support for that is eventually added

BOOK OF VIRTUES

• Add a new wisps registry for having multiple sub-wisps under a single type.
• All wisps are tied to The Princes, a passive that will never spawn a wisp on its own naturally.
• 6 wisp types: Red, Soul, Black, Golden, Bone, and Rotten
• Wisps spawn in the middle ring, have an upper limit of 12, and fire tears with the player
• When killed, Wisps spawn their corresponding attack fly type (sometimes)
• Some wisps have tear effects (Black has Fear, Golden has Midas Touch, Bone has Confusion, and Rotten has Poison)
• Other's Gullet: Spawns two random Fly wisps instead of two flies. Wisps spawn their corresponding attack fly on death.
• Duke's Gullet: When orbital flies are converted into attack flies, they also create a corresponding wisp for that fly type. These wisps do not spawn flies on death, and die automatically after 2 seconds.
• Duke Flute: The friendly Duke will spawn Red Heart Fly Wisps during attacks (1 wisp on small attack, 2 on big attack). Still spawns normal charmed flies on death. These wisps do not spawn attack flies on death.
• Fiendish Swarm (NOT DONE): Spawns Heart Fly Wisps instead of Orbitals on use. These wisps spawn attack flies on death. On room clear, the wisps disappear and turn back into your health.
