B08021 scroll_amount wincap option

> - I'd like to see another option added: scroll_amount. In > combination with scroll_margin, this would control the amount > of squares the screen is scrolled when the scroll_margin is > reached (currently, this amount is 1, but if I recall > correctly, it used to be more). For example, if both were 5, > when you came within 5 spaces of the left screen border, the > screen would shift 5 spaces to the right).
