Message:

messages and debug output converted to PALM routines (restart_data_mpi_io_mod), binary version number set to 5.0, heeader output for restart data format added, restart data filesize and I/O transfer speed added in cpu_measures, handling of single restart files (created with MPI-I/O) added to palmrun, bugfix: preprocessor directive adjusted (virtual_measurement_mod), location message format changed
