Enhance install.sh

Added selection menu to install all steps, or individual
Added reference to autoexec.sh
Added Python Runtime Environment installation workflow

The new Python workflow will allow users to run ENiGMA½ on modern Linux distributions such as Ubuntu 24.04 per my note in #537.

It is my strong recommendation that we offer the user the use of pyenv, as this will decouple the distribution's Python interpreter from that of ENiGMA½ -- this will make the software more portable. It is poor advice to give a user that they upgrade their OS Python Interpreter; doing so can break the operating system if there are incompatibilities.
