Transport Fever 2 - Better Traffic Colors

This mod replaces original Traffic colors with more distinctive ones.

The original choice of pale blue to pale red colors for traffic does not really help to distinguish the different levels of slow downs either on roads or train tracks.
This mods makes colors more vivid and adds a third one (black) to help differentiate at least 3 major levels of jams.

Note that the same colors are used ingame for road traffic jams, train tracks speed and station saturation so these 3 overlays are improved by this mod.
