Removed named params for repositoryNamed(..) from Eclipse dsld (won't
work unless first method param is a Map); changed the param name for
EclipseArguments.include(..) and
InstallableUnitsFromArgumentsHandler.unitsFrom(..) to make clear that
the args are assumed to be EclipseArguments (rather than
DirectorArguments or InstallArguments etc); renamed list() to
listUnits() in DirectorArguments for consistency with installUnits() and
uninstallUnits()
