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.

Paths are transferred by saturnin meta-command so there's no need
to build sub-command binaries

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

Fortify against bad characters in URLs.  This also makes www print one
URI per line (which was intended in the first place).

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