Make Gunicorn respect config.json settings

- Updated gunicorn.conf.py to read host/port from config.json
- Added gunicorn section to config.json for server settings
- Created start_gunicorn.py as alternative launcher
- Updated config.json with server settings (127.0.0.1:6969)
- Updated documentation with new startup options
