Transform Cultists into Blood Cultists before turning them into ghosts

Try to turn entities created by ghosts into ghosts themselves, although it shouldn't happen and this is not tested

Forgot to remove the debug overlay again

Make mod repentance compatible and make the item sprite more isaac-like

Hmm, debug overlay should not be on by default... oops

- Fixed a bug preventing other mods from using the MC_ENTITY_TAKE_DMG callback. Sorry for that! Also please excuse yourself to the other mods creators if you reported a bug due to this issue.

- Behaviors of enemies with children (like heart + mask) is now more consistant when turning into ghosts.

- Fixed a bug where the player could be insta-killed due to ghosts damage being casted to stuff that still could hit isaac.

- Ulcers turn into roundies when ghosted

- Fixed a bug that would flag the mod as outdated when turing Oobs into ghosts.

- Fixed Portal spawners, litle horn's dark ball and ragman's head becoming overly tanky with Lilium Dimension and high luck.

- Black Globin bodies now turn into Gusher when turned into ghosts.

Ghosts turn into ghosts champion variants, to improve their ghostly ghostliness.
