Web server helper for n00bs

[mioux]

This contains helper for running web servers by adding "requirements.txt"
There is 2 bash files. Each one creates a secret key in config.py if not exists, and a venv with required packages

• dev-server-start.sh : starts flask in development mode
• prod-server-start.sh : starts a gunicorn environment for use with nginx (for better security)

(BTW, it corrects multiple line feeds (some are CRLF, some are LF only))
