Execute an external command on the local or a remote machine,

exec_command(["firefox", "http://poezio.eu"]), and this will call
the command on the correct computer.
The command argument is a list of strings, not quoted or escaped in
any way. The escaping is done here if needed.
The remote execution is done
by writing the command on a fifo. That fifo has to be on the
machine where poezio is running, and accessible (through sshfs for
example) from the local machine (where poezio is not running). A
very simple daemon (daemon.py) reads on that fifo, and executes any
command that is read in it. Since we can only write strings to that
fifo, each argument has to be pipes.quote()d. That way the
shlex.split on the reading-side of the daemon will be safe.
You cannot use a real command line with pipes, redirections etc, but
this function supports a simple case redirection to file: if the
before-last argument of the command is ">" or ">>", then the last
argument is considered to be a filename where the command stdout
will be written. For example you can do exec_command(["echo",
"coucou les amis coucou coucou", ">", "output.txt"]) and this will
work. If you try to do anything else, your |, [, <<, etc will be
interpreted as normal command arguments, not shell special tokens.
