Instead of having detailed error messages, run most
commands through a function that calls err() under
fault conditions.
Where detail is still required, err() is still called
manually. Where it isn't, the error message is simply
whatever command was executed to cause the error.
This results in a massive sloccount reduction for lbmk;
specifically, 178 sloc reduction, or a 8.1% reduction.
The total sloccount is now 2022, for shell scripts.

update/blobs/download and update/project/repo both use
the same logic, for setting variables with awk and a
specially formatted configuration file.
unify this logic under include/option.sh, and use that.
