Move Runner plugins code out of Interface::loadPlugins and into Runner

as indicated in Tasks.

A simple static function does the job IMHO, but if we want something
like a RunnerLoader/Trader class (which can also load a specified
single runner?) I can work on that.

One more question in mind :). Should we make all runners loadable in
runtime?
