CMDHELPER-2789 - Reported by MariuszT

I saw that jb_aero began to add this event. Today I tried to add the necessary code but got lost. Jb_aero, is there a chance that you finish this event? I need it to prevent players add injuries to other players in non PVP areas. Here is a nice tip how to do it with this event https://forums.bukkit.org/threads/setting-affected-entities-with-the-potionsplashevent.111007/.
