WetFX road surface for "LA Canyons" new1

Since the model of the roads in the new LA Canyons differs from the old one I remade the wetFX overlay. Also added in this package is the physics enabled cracks overlay. The strength of the effect is configurable by editing "..\content\tracks\la_canyons\wet\data\surfaces.ini"

"VIBRATION_GAIN" is the amplitude of the effect and "VIBRATION_LENGTH" is the frequency.

NB: You don`t have to download this if you have the updated 2-way traffic.
