Improved ways and building positioning based on gps trace.

Added explicit Stop sign and zebra crosswalk to dangerous intersection. Stop sign at other end of way. Slightly shifted ways to match new GPS track.

Added preliminary changes: newly 2-way driveways, parking lots, new buildings, businesses, and new street parking lane. My GPS tracks were bad, so this is best-guess data to be fixed later.

Merged signals, as it's just one large intersection.

Added leg to the Canal at Whitehall intersection to reflect recent construction.

Straightened into a T to reflect permanent intersection reconstruction.

Add road surfaces
