Version history now shows each dimension in its own unit

When you compared two versions of a product, its length, width and height were all converted into one unit, so a variant kept as 2.778 yd x 100 in x 254 cm, the same length written in three units, read as 2.777778 yd on all three. The comparison now shows each measurement in the unit you chose, exactly as the products list does, and a version that only changed the unit a measurement is shown in no longer looks like a change to the size.
