Allow passenger seat on cart dragged by mounted pet
If cart is dragged by mounted pet, set flag to have passenger seat. That would allow new player to hitch ride and get safe to village he want to join. If i have tribe somewhere south, and potentional player is somewhere far, can get to him fast with my cart and pet and transport player and his possible bellongings with his bins safely to my place. So only if cart is puled by mounted pet. If "driver" disnount, passenger dismoundt from cart too and can get back on passenger seat only when i mount pet and use cart again. There are players who already collected some stash they don't want to leave while moving to others tribe and even with pulling cart is slow and very dangerous for them to travel far
