Depot Co. 1.22.2: the main hall lights again

• The main hall lights again. Since 1.22.0 the hall's ceiling lamps, the office, the break room and the yard lamps stayed dark at every hour: the engine handed the lighting three of its four values and the power switch never arrived. They light at night and go out in a power cut, as before.
• The traffic cars on the road have whole wheels that turn, arches along their sides, and windscreens that lean the right way.
• Under the hood: Co Engine v0.5.2. No other change for the player.
