Fixes to Venom Sword and Hyposprays

Created by: Shadowmech88

The venom sword can no longer be crafted using an autoinjector. Removing a hypospray from a venom sword no longer refills the hypospray with DD. The creatine hypospray now actually spawns filled with creatine instead of DD. Fixes #8364 (closed).

Fun fact, autoinjectors containing 5u Doctor's Delight is apparently a bug. Based on the code in /autoinjector/New(), autoinjectors are supposed to be filled with 5u inaprovaline. Of course this would be terrible, so I've just removed autoinjector's New() since it currently has no effect anyway.
