Changes since 1.4: +3 -2 lines 
o bridging the gap between eddy stress and GM.
  -> eddyTau is replaced with eddyPsi (eddyTau = f x rho0 x eddyPsi)
      along with a change in CPP option (now ALLOW_EDDYPSI).
  -> when using GM w/ GM_AdvForm:
      The total eddy streamfunction (Psi = eddyPsi + K x Slope)
      is applied either in the tracer Eq. or in momentum Eq.
      depending on data.gmredi (intro. GM_InMomAsStress).
  -> ALLOW_EDDYPSI_CONTROL for estimation purpose.
  The key modifications are in model/src/taueddy_external_forcing.F
