EffHealth include damage from Entity

[TheLimeGlass]

Description

There currently isn't a way to set an Entity as the source of the damage in EffHealth https://hub.spigotmc.org/javadocs/bukkit/org/bukkit/entity/Damageable.html#damage-double-org.bukkit.entity.Entity-

[Snow-Pyon]

The problem here is that we don't actually damage the entity, it justs sets their health. The way Skript handles that would have to be changed for this to work and since we don't want to break anything at moment, we'll have to see what we can do about this later.

I believe #7878 solves this
