Added Flaxbeard's Steam Power

I disabled copper and zinc generation since we already have that. We'll
need to go through the rest of the config to see if there's anything
else we'd like to alter. Closes #46
Added HatStand

It has no config. Closes #39
Added Opis and Mobius

Opis command only useable by admins. May be changed in the future.
Closes #44
