For CAS-14567, in EJones.cc, EPowerCurve::specify(), reshape gain coeffiencient Array to have a degenerate channel axis, so that resulting caltable is generally conformant (FPARAM col has shape [npar,nchan,nrow]). In SolvableVisCal::listCal() and ::writeHeader(), various improvements to listcal formatting to better support rendering EPowerCurve listings, and added proper formatting support for fringefit caltables, including some scaling/unit juggling so the printed values are sensible. Also cleared up some (otherwise inconsequential) compiler warnings in SolvableVisCal.cc.
