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.
