Added ability to edit a unit, except for sort/walk order. To handle those things we'll need to: save unit's old sort/walk position; adjust down (by one) all unit positions greater than the old position; adjust up (by one) all unit positions greater than or equal to the new unit position; update the unit's position. I'm not going to worry about it right now.
