Smoothness constraint now enabled also for initial T, S
This has changed flags slightly; now use
o at compile time:
  * ALLOW_SMOOTH_IC_COST_CONTRIBUTION
  * ALLOW_SMOOTH_BC_COST_CONTRIBUTION
o at runtime
  * mult_smooth_ic

222     c The individual cost function contributions are multiplied by
223     c factors mult_"var" which allow to switch off these contributions
224     c without removing them in the adjoint code. This is useful for
225     c doing tests with the adjoint and perhaps useful in assimilation
226     c experiments where individual contributions are successively
227     c switched on. For future applications it would be better to place
228     c the initialisation of the multipliers somewhere else, for example
229     c in a namelist, which is read in at the start of the model.
