[MIRROR] Medical Tweaks

Original PR: VOREStation/VOREStation#3942

Minor balance changes and tweaks. The syringe infection chance tweak is probably the biggest change.

• Advanced Trauma Kits treat 7 damage per application, and are now used only once per body part (instead of once per wound like gauze)
• Advanced Burn Kits treat 7 damage per application
• Medical Rescue Suit injector now has 20 units per chem, and uses Inaprovaline, Dylovene, Paracematol, and Dexalin
• Bicard effectiveness reduced from 6 damage per unit to 4 damage per unit
• Kelotane effectiveness reduced from 6 damage per unit to 4 damage per unit
• Dermaline effectiveness reduced from 12 damage per unit to 8 damage per unit
• Dexalin metabolizes at 25% of the rate of Dexalin Plus, stats adjusted so that the effects are the same, just that it takes longer to wear off (Natje's suggestion)
• Reduced brain healing of Alkysine from 30 to 8 per unit
• Vermicetol is now a T2 brute chem, healing 8 brute damage per unit and metabolizing at normal rates
• All pre-filled syringes start capped.
• There is now a 20-second grace period where infection chance is 0 (Note: Using syringes on multiple people renders grace period null and void)
