[Martin Losch]

Hi Patrick,
I do have now a working version (at least its passing the verification  
experiments) where the 3D seaice fields are completely removed. I will  
check it in, tomorrow that latest. I am just waiting for JMCs  
confirmation, that I understand the seaice_read/write_pickup correctly.

I think the major problem that I introduced is in advect.F: I  
introduced a loop with length 2 to save some code for the modified  
Euler time step (and the same for the obscure diffus calls), similar  
to what I have done to seaice_lsr.F. If it's really a problem that  
please go ahead an unroll the loops again. This part of the code is  
not affected by the yet uncommited changes, but do wait with this  
until I have checked in the rest.

Martin
