Remove requirement for NET2, added requirement for 2-Lane Two-Way Bus-Only Road by Delta 5-1. Recommended usage with Traffice Manager: PE by LinuxFan, but not required.

Four-Lane roads at intersections have been updated to a vanilla four lane road instead of the previous NET2 Four-Lane Road without median and instead of having four seperate turnouts for the bus area, there is now only two. Added some additional folliage, base game, to the center of the roundabout.
