Finished saving the roomGrid (boardCell[][]). I am iterating down the y
and for each row and for each boardCell I am saving it like this: (x,y,
GameObj id, groundType) then adding it to an element. I've decided to
just save the GameObject id because I am saving all the details of all
the game objects that are in RoomInventory anyway and so when I load the
game I can look up those objects instead of saving them twice.
