added regolith path

I added the i3 config path used by regolith for my convenience, but thought I'd share back to the original if you want to have it also. Thanks for the script :)

Hmm you might actually not want to pull this now ... I realized the script is giving bad outputs on my config. E.g.

One of the two is actually $mod+$alt+z, my second commit is an ugly fix for this, but I did add a nicer sorting (by command length, and grouping binds ending in a named key together).
