A Python Generator

We can now change skript.js via python.

This means:
- Using either `./generator.py` or `python3 generator.py` will run the
  script to make a new spacebar and card.
- skript.js can be used after the generator.py script has ran, and
  should be ready for deployment... (Once CSS sanitation is done)
