* nsf.c (ParamOptionParse, ParamDefinitionParse, ParamDefsParse), parameters.test: Small "type=" converterArg reform. Provided additional parameter in param-parser machinery, to communicate a (namespace) qualifier into ParamOptionParse. This way, the unqualified type=* values are now expanded to qualified names (definition scope): method parameters, nsf::is, nsf::parseargs, setter methods. Type=* in object parameters are currently expanded at the slot level, could also be added. New tests were added, existing ones adjusted to reflect the new behaviour.
