Ninja Death-splosion fix

Ninjas will now explode on death without an explosive implant that doesn't work and can be triggered by the Ninja's own EMP or shitty death checks on every human. They will also gib with their gear deleted on exploding. This is because I feel like Ninjas, if they have something like a martyrdom, should be permanently dead after it activates. The gear is deleted to prevent people from putting on things that have a canremove of 0 with no way to turn it back to 1 because the gibbing destroys the suit.
