- in dynsolver set zMin = 0. in anology to seaice_dynsolver

change a lot of things at the same time so we can never trace the
changes individually (should not affect the adjoint, as it is
generally not using the LSR solver, right?)
 - fix bug in metric terms of u-equation in LSR solver (implicit part),
   changes verification/lab_sea
 - rearrange implicit part of u-equation in LSR solver to make it easier to
   read, understand, and debug. This causes changes at the truncation level.
 - fix (serious) bug in the boundary conditions (sign error in the implicit
   part) of the LSR solver. Changes all LSR results
