+Add timestamp and directory to particles restart

The directory, time and timestamp variables are needed by the particle code in order to write better restart files. I have changed the particles_save_restart interface to add these variables. I have also removed the option to pass temperature and salinity to particles_save_restart, because these variables are not useful for restart.
