#178: New command that runs non-interactively

Comment (by Roland Haas):

As of git hash 868ec6aa "simrestart: duplicate log data to file in sim run" of simfactory2 one can use:

nohup sim run --parfile foo.par &>/dev/null &

or one’s favorite equivalent for this since run duplicates output to both stdout and the simfactory foo.out log file.
