[Update] Possession Sphere

12/09/2025 - DeVloek:
- Rewrote the ACS and most of the DECORATE from scratch in Zscript
- The ghost no longer targets barrels and now passes through them
- The ghost is no longer destroyed when hitting surfaces, instead it bounces off and is destroyed after 20 seconds
- Improved seeker code, now the ghost seeks new targets when the current target is already possessed or shouldn't be affected otherwise 
- Slightly increased the ghost's speed, homing range and turn angle
- Added a "maxcharges" property to the ghost. Now it can continue seeking out monsters to possess until all charges are used
- Added an "allowbosses" property to the ghost, this determines if monsters with the BOSS flag should be affected or not
- Added dynamic possession duration based on monster health (can be toggled off so the original 45s duration is used for all monsters)
- Monsters now always play their SeeSound when aquiring new targets after being possessed or waking up from possession.
- The possession indicators are now particles instead of actors
- Added dynamic lights to the ghost projectile and possessed monsters
- Adjusted ghost sprite offsets to make it look less jittery when flying
- PNGcrushed sprites
- Added MAPINFO with a DoomEdNum
