Alpha Dublin 0.31

Hi, all! This small patch fixes the right-hand-drive ETK 800, which formerly just sorta exploded on spawn. Also, the normal LHD gauge needles won't poke through the dash, so that's a plus. The map this time around isn't any bigger than in previous updates, but I've added some extra detail on several facades around the city.

I've also had to remove a few older scenarios, as they no longer work. But there's a new police chase scenario to play!
