Bundle a "stand alone" version of Python for each target OS.

[ntoll]

See https://github.com/indygreg/python-build-standalone for how to create such stand alone versions of Python. Ensure tkinter is part of these along with turtle, and we're able to create new virtualenvs within the user's home directory, and pip install things into them. Bonus points if we can get pygamezero, black and jedi to run with it. This needs to work on Windows 64bit, OSX and Linux.

Commit 0263d7c adds the capability to automagically download the latest stand-alone versions of Python from @indygreg's https://github.com/indygreg/python-build-standalone project.

Next steps:

• Integrate this into platform specific build scripts for generating Electron apps for each of the supported platforms.
• Create and ensure this all happens as part of the CI/CD pipeline.
• Investigate Brython as a solution for running Python in the browser based version of Mu-naco. 🐍 🕸️ 💥
