Log Message:

- replace d_AREAbyOCN with d_AREA, which is now split in d_AREAbyOCN/d_AREAbyATM_cover/d_AREAbyATM_open
- simplify notations -- d_HEFFbyOCNonICE->d_HEFFbyOCN, d_HEFFbyATMonOCN-> d_HEFFbyATM, etc.
- introduce SEAICEareaFormula run time parameter, which selects the recipe for
  computing the ice cover tendency from effective thickness tendencies. It ranges between 1 and 3:
  -SEAICEareaFormula=1	default in LEGACY branch
  -SEAICEareaFormula=2	default in EVOLUTION branch
  -SEAICEareaFormula=3	Ian Fenty's recipe
- remove 'undef SEAICE_OCN_MELT_ACT_ON_AREA' which may now be achieved using SEAICEareaFormula
