ai hints and camera for pre war spa 1.0

this reduces ai crashes and also corrects the track side camera set. I only made one camera set so you might want to rename cameras_1.ini to something else or delete it.
tested with 1923 and 1967 gp cars.

NOTE: This is NOT for the THR(?) version with a tighter malmedy chicane

spa 66 will be released soon after more testing.
