New death effects to appease the god

[Mercerenies]

• [X] Dying to Herobrine (achievable by having "Herobrine" appear in your death message. So dying to a mob you've name tagged as Herobrine works.) (Done by 4cc50fa)
• [X] Dying to Redstone (unsure if you could actually track this, but basically using redstone to finish yourself off.) (Done by fbc5720)
• [ ] Jump multiple times (it would track how many times all players have jumped. If the amount becomes equal to or greater than playersX60 (at least 60) then that gods are appeased. Note that the amount of jumps required is chosen when the gods decide to use this challenge.)
• [ ] Spend time in water (this one will keep track of how long players are spending in water. If the amount of time spent becomes equal to or greater than playersX15seconds then the gods are appeased. Note that the amount of time required is chosen when the gods decide to use this challenge.)
