Changeset 4131 for palm/trunk/TESTS/cases/urban_environment_salsa/INPUT/urban_environment_salsa_chemistry

Several changes in the salsa aerosol module:

• Add "salsa_" before each salsa output variable
• Add a possibility to output the number (salsa_N_UFP) and mass concentration (salsa_PM0.1) of ultrafine particles, i.e. particles with a diameter smaller than 100 nm
• Implement aerosol emission mode "parameterized" which is based on the street type (similar to the chemistry module).
• Remove unnecessary nucleation subroutines.
• Add the z-dimension for gaseous emissions to correspond the implementation in the chemistry module
