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)

not entirely sure if this is a good thing or a bad thing but keeping it a subtype of pens is the simplest solution so i'll go with that.
