Added a shell script runner for Mac OS operating systems.

Just run mac.sh to run up.

this is untested as i dont have a recent Mac to try it on.

So the tool can be ran on Windows, Linux, Mac OS and Chrome OS (with Linux Subsystem installed).

The first time running, you may be asked for a password to install python add ons needed to run the main program manager.py.

running in the future will quickly check for installed add ons then open up Manager.py
