Races and map improvements

I’ve been working on a variety of things lately including adding races (industrial, small island and dry rock island all have a variety of races and the last two have both point to point events and circuits) and new race-related objects to the current maps, polishing the new East Coast map and improving the existing ones like Dry Rock Island. Here’s a before and after pic showing the new tropical ground cover (thankfully far less radioactive than the last stuff).
