Merging seaice_growth codes -- part 3 -- the merging, at last.

This check-in completes the overall 10/2010 revision and merging process, by

- adding a header that explains unit/sign/naming conventions.
- introducing areaMax parameter that is, for now, hardcoded to 1.
- re-including the 'vintage bug' as a comment -- in case I got it wrong.
- bracketing 'IF (useRelativeWind)' with '#ifdef ALLOW_ATM_WIND'  
  consistent with what pkg/exf does.
- merging the '_if.F' features that differ from what is in legacy code:
   - option to actually grow ice over open water, which legacy code 
     only virtually takes into account in the area tendency (I think).
   - let melting by ocean reduce area (as melting by atm alone does in legacy).
   - different criteria for rain->snow (incl. as comments).

The added features are bracketed out of legacy code, so this 
revision did not affect forward results. A couple cosmetic modifications
changed adjoint results by only three digits. I will only update those.
