Move parameters from driver.F90 to namelist (#2)

Add support for defining most parameter-specific values and activate/deactivate switches from driver.F90 to a namelist file named input.nml. Only a few rarely-changed parameter-specific values belonging to the "Declarations of local variables (INPUTS)" section have been left in but can be added to the namelist and removed from driver.F90 at a later stage.
