The previous version actually meant "create backup config.mke"

To maintain safety of colision and reflect purpose ('ffoo/saturnin_www.sh'
vs. 'libexec/saturnin-www.sh'), adding prefix 'saturnin_'.

No need to maintain module for one function; moved to saturnin-www; the
only user so far.

Config files can now be merged from 4 sources:  distribution-provided,
(share folder), local (/etc/saturnin), user-specific (~/.saturnin and
~/saturnin/ini.d/*)

Move cub-command to libexec path to prevent calling them directly,
allowing for better control of environment.

Increase readability: decrease complexity of the build function and
preserve wandering off too much against 80-char "buoy"

Make it easier to share &  sync installer code across projects from the
same family.

A dmenu wrapper to leverage inireader for easier work with style
configuration and to compose key/value based menus.

To simplify extraction of eecc config outside ffoo-enabled scripts
(e.g. from inside *rc file).

All other files have been moved to *fastfood* and whole qecc
history (~300 commits) has been squashed into this commit.
