Implemented implicit vertical diffusion (tracers only).
Involved introducing a "total" diffusivity array (local 3D)
calculated by calc_diffusivity().
Made some small changes to time-stepping algorithm.
Switched on by setting implicitZdiffusion.
(note: *Not* fully tested with topography. But when switched off
this does produce identical results)

Swapped the time-stepping algorithm around (just a little bit).
We now officially use the predictor-corrector terminology.
We make the prediction step at the end of the dynamics() section
and store the result in the gUNm1, gVNm1, gTNm1 arrays.
The "tricky" part is that at the beginning of the dynamics section,
where the "correction" is made, theses arrays must be initialised
at the beginning of any run. A new routine init_predictor() does this.
This is "all" in preparation for implicit diffusion. Let's hope
it's enough...

Moved the "K loop" from timestep() upto dynamics(). dynamics() now
contains all K loops (two infact).
