Log Message:
o OBCS and PTRACERS: add open boundary support for passive tracers
  - either use homogenous (pseudo) v.Neumann conditions or prescribe 
    OB-values from file; this is not different from the way theta and salinity
    are treated
  - however, Orlanski-radiation conditions are not supported, and the model
    will stop if you use pTracers and Orlanski at the same time. 
  - beefed up the rountine obcs_external_fields_load: now only those open
    boundary values are overwritten with values from files for which there 
    are really files, otherwise the OB-fields remain untouched. This makes
    it possible to use different OBs at different ends of the domain (as 
    with EXF)
  - TODO: add support for OB?w and OB?eta, which can currently not be read 
    from a file.
