Boy/Girl option

This adds the boy/girl selection from later generations, using the pret tutorial and a spriteset from Pokemon Anniversary Red. I made some alterations, namely inserting the option later into the speech to be less clunky, and having the Nidorino become a Nidorina if you pick the feminine option.

I decided to make the third name option Seren, a common Welsh name for girls. It means "star", which is really cute! But...most people will probably say it's a Panel de Pon reference, which is cool too.
