roof:color <-> roof:colour / building:color

[rza31]

The validator note that roof:color and building:color is out of date.
I suggest to repair automatic to roof:colour, building:colour. It is just a syntax correctur.

From deprecated.mapcss, #10329:

*[/:color/]{
  throwWarning: tr("{0} is deprecated", "{0.key}");
  suggestAlternative: ":colour";
  group: tr("deprecated tagging");
  assertNoMatch: "way color=red";
  assertMatch: "way roof:color=grey";
}

Anyone knows if one solution is faster?
*[color][colour][tag(color)=tag(colour)] vs. *[color][colour][color*=colour]

In 13788/josm:

fix #15877 - autofix roof:color and building:color to roof:colour and building:colour (as long as not both keay with different values are present)
