Actually, I remember why I kept this now. Unifying damage text across all attacks means that the text we print shouldn't specifically branch on gender. It's much better to print "The <thing> <attackverb> <pronoun> <weapon> <target>" than to print "The <thing> <attackverb> his/her <weapon> <target>" and to case it by gender, because not everything that attacks has a gender.

To allow the previous idea, I'm planning on adding a `Creature::possessive_pronoun` or something similar to handle cases like this, but obviously haven't yet. Either way this is a really easy change to revert, so I'll do that anyways.
