Paintable Walls/Window Frames

[WickedCybs]

Now that we're getting into mapping entirely new ships and away sites, one stumbling block I've always found is that everything is either the same colour (steel/rwalls) or a custom wall type to get past that to an extent. It would be a lot easier though I think, if we could just have our core type of walls be colourable (maybe add a painter?) and it would help with mapping too and making it so things don't need the effort of custom sprites while still still looking different.

This is easier said than done of course but as someone getting into mapping, it'd certainly be appreciated, at least.

I'd like this if you could colour them on each open-facing side differently, though the sprites may require adjustment for that to look good.
