Unsupported Driven To Destruction: Eve Events V2.2

Some fixes noted during some reviews and further testing (big update with many more scenarios out in due course of his one )

• Fixed trees not disappearing in some scenarios (not 100% guaranteed to work)
• Fixed the names of the point-to-point races

(The following are for the p2p supercar scenario):

• Removed the grass in the warehouse so that it looks much more cleaner
• Fixed the supercars not being able to enter the warehouse
• Correct the waypoint length of the supercar scenario.
• Increased the size of the waypoints to be more triggerable and lenient
• Made the AI actually finish the race, rather than stop in the warehouse
• Increased the I path leniency so that the AI can take a safer route and the make the scenario competitive
