Add Rainbow Paint and Vehicle Jump

[Ethereal-Business]

Note: Both of them have some formatting from the legacy YimMenu code, however the rainbow paint feature is missing the tire smoke and neon features.

Vehicle jump is almost word-for-word from the legacy YimMenu code.

It would be good if you add these features in a separate tab ("Misc") inside Vehicle.

So, when creating a slider,

This is not the way to do it: static IntCommand _RainbowPaintSpeed{"rainbowspeed", "Vehicle RGB Paint Speed", "Speed of the rainbow paint cycling (1-10)", g_RainbowPaintSettings.speed, 1, 10};

This is the proper format: static IntCommand _RainbowPaintSpeed{"rainbowspeed", "Vehicle RGB Paint Speed", "Speed of the rainbow paint cycling (1-10)", 1, 10, 1};

Now the slider actually works. Don't just copy and paste, actually adjust it to other feature's code.
