Adds some useful ores.
Mods introducing new content into the game.
New Ores and resources as well as machines.
Change the default behavior of the optional ores so that they show on the map generator screen but are disabled there.
Not sure if I should or not...
I mean, in theory things are set up in such a way that mods turn ores they need on... however, I'm not sure if any mods other than bobplates even use this anymore.
