This new patch fallsback to the next older available daily d-i instead
of returning an error when "lb config" is executed.
Also, the security mirror is set to snapshot date (it wasn't in the
previous patches).
TODO:
* "mute" wgets;
* update man pages;
* clean code (variables and function names, messages, etc)
I'm not happy with the functions and their names. I created them while I
was creating the patch. They surely need some rework to meet live-build
standards.
