Subject: [PATCH] treat colors like the other parameters: only copy them from
 the palette color group /sim/hud/palette/color[*]/ to the active group
 /sim/hud/color/ if they really exist. (Parameters like <antialiased> can be
 set in the active group and be left alone, or set by each <palette> color
 group.)
