Class midpoints to match parent way and adjust styles.
After editing more with 1.5.3, I really dislike the more visible
midpoints I added in afa1efd.  This commit gives the midpoints
tag classes so that we can style only *certain* midpoints more visible
(footpath, cycleway, bridleway, etc) and leave all the others dim.
