changing project script using Python instead of Js

[nerdoc]

Enhancement

Description

sockpuppet needs to (globally) install add-project-script Js library temporarily during initialize mgmt command. This leads to some difficulties, slows down the process, and is error prone.

Fixes #115 It's faster, less dependencies, easier.

Please don't pull this PR yet, as it is still a WIP. @jonathan-s please tell me what you think, and @sagannotcarl maybe you could tell me what you say about that.
