[ENHANCEMENT] Apache missing ssl mod for using HTTPS connection

[robinduerhager]

Hi,

when trying to use SSLEngine on in the apache2 config inside the docker installation, it declares the line as a syntax error which won't let us use Hashtopolis with a secure TLS connection. I went into the container and executed a2enmod ssl && service apache2 restart which helped me out, so i guess adding a a2enmod ssl to the dockerfile will do the trick here.
