Greenmine/install

The previous draft of installation instructions is here, for reference. Ferreteria is now included as a submodule of Greenmine, which affects folder locations and negates the need to clone it separately.

I'll use the following shorthand:

• <www> = the public HTML folder (typically public_html or www)
• <gm> = the Greenmine base folder (I usually put it at ~/site/git/greenmine
• <uhome> = the home folder for the domain's files (outside of <www>)

Action / Intention	Example Commands
Set up folder structure	cd <uhome> mkdir site cd site mkdir git
Install Greenmine & Ferreteria	cd git git clone git@gitlab.com:woozalia/greenmine.git
Make soft links from www to greenmine/
