hades_columnia adds many column-like variants for nodes
and a columnia workstation to craft them.

History:
The mod was previously named 'columnia' in Minetest Hades.
This is a fork of DonBadman's MyMillMaschine, which is WTFPL-licensed.
But the "placing" code is a part of the stairs mod which is LGPL v2.1.
