The Out-only converters shouldn't need to implement loadFile(), as it shouldn't be called - a converter is not used for input unless it says it supports input. At the same time, provide the "ground state" implementations for optionsHelp(), outputOptions() and probeFile() to save the trivial implementations the need to duplicate one another. In the process, make the handling of loadFile()'s outputConverter more consistent among those that do implement it. Always set outputConverter if it's initially null (the caller does assert this).
