New:
---
humidity=.T. is now usable for runs with topography. wall_humidityflux and 
wall_scalarflux are the corresponding new parin arrays.
(check_parameters, init_3d_model, parin)

Large scale vertical motion (subsidence/ascent) can be applied to the 
prognostic equation for the potential temperature. (check_parameters, header, 
Makefile, modules, parin, prognostic_equations, read_var_list, subsidence,
write_var_list)

Changed:
-------
var_ts is replaced by dots_max (modules,init_3d_model)

init_3d_model, modules


Errors:
------
Bugfix: exchange of ghost points for prho included (time_integration)

Bugfix: calculation of time-averaged surface heatfluxes (sum_up_3d_data)

Bugfix: calculation of precipitation_rate (calc_precipitation)

Bugfix: initial data assignments to some dvrp arrays changed due to error
messages from gfortran compiler (modules)
