Preset Colours on Paintguns / Paint Walls

[WickedCybs]

I'm on a roll.

Essentially, just the title. Give paintguns an additional option that allows them to select colour presets. That way rather than using a colour picker or eyeballing decals on the floor, you can just directly select something like medical decals if you have to repaint medical's flooring a bomb explodes or whatever.

Also it'd be nice to be able to repaint walls now that those are designed to have different colorings now.

This would be especially helpful for colourblind players. If I need to come up with a colour on the spot without taking the colour from an existing object or turf, eyeballing the right colour from a colour wheel is extremely challenging.

The paint gun's colour picker is pretty useful, tbh, but I don't see a reason why we shouldn't do this.
