Rns

Added `-A` command line option. This listener option causes the
remote command line to be appended to the arguments list of the
launched program. This allows the listener to jail connections
to a particular executable while still allowing parameters.

What's Changed
* Fix running initiator from a script/pipe by acehoss in https://github.com/acehoss/rnsh/pull/1
* Remote command line options by acehoss in https://github.com/acehoss/rnsh/pull/2

Remote command line and pipe compatibility
Command line options have changed somewhat to allow the initiator to supply a command line. This allows `rnsh` to function similarly to SSH. You can pipe into or out of `rnsh` to send input through remote commands or remote command output through other commands.

This behavior can be blocked on the listener with the `-C` option.

When the initiator does not supply a command, the listener uses a default command specified on its command line. If a default command is not specified, the listener falls back to the shell of the user it is running under.
