Major clean-up

[theredwillow]

1. gitignored pycache's: these files are auto-generated at runtime, no need to track them
2. deleted routes.py: unused routes import made no sense in init_.py. could probably still be improved upon
3. passing cards as whole objects: no need to pass a gigantic block of variables to the templates when card already defines most of this stuff
4. simplified cards.py -> deck.py: many of the functions could be rewritten much more simplistically
5. established card.css: a first step towards separating style concerns
6. created json files to read: separated content concerns such as card definitions and reading list suggestions out into their own static files
7. reformatted files: sorry, I didn't know what formatting you were using. added TODO about adding config files for just that.
