Subject: [PATCH 1/3] Update Dockerfile to set variable CS2_IP

The variable CS2_IP will be used in entry.sh for cs2 parameter "-ip" to set the tcp listener to a specific ip address.

default: 0.0.0.0 (listen to all IPs on the local machine) is probably the best.
left blank: cs2 try to identify the current ip automatically
