Right now there is code to dump the options values to the log file. This code has proven difficult to maintain (as new options are added, they may not also be dumped; as further plugins or other features are developed, those extensions and their parameters may not be written).

#379 allows for outputting options to different formats. One format can be LOG format. This method can (or perhaps mostly can) replace the existing mechanism Options::Dump method. Further work with the Options infrastructure may allow the internals to be completely replaced with this methodology.
