Villager price change strikethrough is the same length regardless of the number of digits in the price

The bug

The graphic displayed over the old price when a villager's price has changed is the same length regardless of whether it has one or two digits, meaning it's either awkwardly too long for a single digit and not quite long enough for double digits.

How to fix

Either the texture should scale dynamically using the new nine_slice system, or separate texture files should exist for one digit and two digit prices.
