nice behaviour of the top snow layer. Merge only suppressed now in
case both miminum ice criterion and minimum element length are met.

|7 years 4 months ||Non convergence in soil freezing is now treated as a warning,
instead of an error, because we try to repeat the time step with a
smaller time step.

confusing (has basically nothing to do with alpine3d), I renamed it
to SNOFILE. Then, it takes the grain size specified in the sno-file
to define the soil types. This should be the default option. I also
