- Automatically write a mapcolors.txt file for use with minetestmapper if infodump features enabled. - Define colors for terrain mod and "below" lexically, and for anything that inherits from it. This will allow mods to register colors to use on the mapper automatically, and benefit from inheritance where material inheritance is in use, rather than having to have each mod distribute its own text file and mapper users having to collect them all together manually.
