Add python version files

[fozcodes]

For we poor souls with multiple versions of Python in our system. This tells things like pyenv which python executables to load automatically.

The sqlite package in the server depends on Python 2 and most people are running Python 3 these days.

The client had a package that also needed Python 2, but I've lost my console logs there and can't remember. Either way, never hurts to be explicit.

Cheers!
