Function InterpretKey

* Parse "name", "section.name", "noname", "section.noname" settings keys. * * @note Where an option was negated can be later checked using the * IsArgNegated() method. One use case for this is to have a way to disable * options that are not normally boolean (e.g. using -nodebuglogfile to request * that debug log output is not sent to any file at all). */
