Neither plParticleGravityApplicator nor plParticleDragApplicator have class indexes that exist in the list of class indexes, and they are not registered as creatables. Most linkers seem to handle this fine by just removing the classes entirely since they are unused, but I've seen errors about the missing class indexes on a few systems.
Since they are unused and have no working implementation, let's just remove them to avoid any potential linking issues.
