[TF2] It's possible to survive the Half-Zatoichi one-shot

[JoriKos]

Though this is mostly specific to Mannpower, it's possible to survive the supposed one-shot of the Half-Zatoichi if you're also wielding the Half-Zatoichi. A simple fix is in tf_weapon_sword.cpp at line 562 to increase fDamage from pTFPlayerTarget->GetHealth() * 3 to a larger value.
