Consistent docs and project structure

[TheLonelyGhost]

This is a multi-project set of PRs:

• Consistent docs and project structure #3
• Consistent docs and project structure tor_archivist#2
• Consistent docs and project structure tor_core#10
• Consistent docs and project structure tor_ocr#8
• Consistent docs and project structure tor#62

All of these pull requests center around the same concept: updating documentation and tooling to be a unified front.

• waffle.io badges were used inconsistently
• some references to the repository A when repository B was the intended target
• messy dependency tracking
• license files varying between LICENSE and LICENSE.txt, referencing a copyright holder as TranscribersOfReddit, which is not a legal entity.
• ... and so on

This merges all of that into a set of clean instructions, descriptive... well, descriptions, and making as much use of setup.py as possible (instead of the split standard with requirements.txt).
