upload shit

Note: I switched to Gunicorn at some point because Bjoern was somehow annoying. Don't use run.py, use

gunicorn -b localhost:5000 -e SCRIPT_NAME=/upload fileHost:app

Dependencies:

passlib argon2_cffi flask gunicorn flask-paranoid apscheduler requests

This application makes use of the secrets module (a cryptographically strong version of random) from the standard library, which is only available in Python 3.6+. If you really can't be bothered use the latest version of python3, or just don't want cryptographically strong random character filenames/prefixes for some reason, you can directly replace all instances of secrets with random.
