Implemented rolling release support:

- Now basing on image 'kdelfour/supervisor-docker'
    - Cron script will check and update TT-RSS and all plugins on a daily basis automatically
    - SSL/TLS encryption is off by default so that TT-RSS is running on port 80 by default now
    - SSL/TLS can be enabled with setting "-e TTRSS_SSL_ENABLED=1"
    - A lot of cleanups
