Removes the parapen and replaces it by a refillable chemical pen.

Also buffs the hypospray to contain 50 units and gives it the ability to inject more than 5 units at a time. (To adress complaints that a chemical pen would render the hypospray obsolete, and it's not like the hypospray is incredibly OP)

The same ones as reagent_container's parent type. Not exactly sure what those are, but they range from 5 to 30 (yes I did test it, I just didn't memorize every number)
