Material science: The Effort post II

[Frank_Stein]

There's still a bunch of weird things with parts of the station not having a material type set. Cutting grills and rwalls will give you a null material rod, and when you lift up a floor tile (which is steel by default) and plant it back down, you've instantly darkened the area. While that's great for making a repaired area look obviously distinct, maybe steel's colour should be lightened to the default wall/floor/material colour, and everything that's already "made" of it should have that material flag set?

Yeah, that bugs me how mauxite seems to be the default metal but doesn't match.
