[Skyblock] Give grass the same island value as dirt

Me and @Ancienty placed a lot of dirt in our island and our island level was around 2k, but then all the dirt turned to grass and since grass has no island value, our level went from 2k to 500 or something around that. My suggestion is to make grass give the same island level as dirt (1) because a lot of people from the skyblock community I've talked with today doesn't like this and gets annoyed when it happens.
