Changeset 2861

Small modifications for restart variables:

• Add missing initialization of temp_growth in stomate_initialize. This variable is needed in diffuco. => small change in results expected for the case ok_co2

• Remove raero from restart file. Change it to become a local variable in diffuco_main. This variable is only used for diagnostics.

• Remove temp_sol_new from restart file. temp_sol and temp_sol_new is the same in the end of a time step. Therefor only one of them needs to be in restart file.
