* Use docker image caddy:2-alpine
* Caddyfile: remove "limits 10KB"
* Caddyfile: URL /filtron/rules removes (filtron API still availabled on http://localhost:4041/rules )
* caddy storage are docker volumes (caddy-data and caddy-config). start.sh and stop.sh have been modified to keep these volumes.
* .env: Remove SEARX_PROTOCOL, SEARX_TLS, FILTRON_USER and FILTRON_PASSWORD variables.
* docker-compose.yml: filtron and morty listen on 127.0.0.1 (related to #38)
* Fix#37: settings ```SEARX_HOSTNAME=localhost:8888``` works as expected (https connection)
