syntax highlighting.

It now looks for a "dry_run" keyword argument, and if one is
found with a true value, errors are not written to the
database.

The transfer directory in the configuration file is now the
base e-transfer directory, with the new, replace and reject
directories inside.

empty if there were no input files.
