Add support for two servers. This is a breaking change from before, as it creates new volumes with 1 and 2 in their names, allowing for 3, 4, ..., n.

 ## Stopping the server

 To stop the DayZ server:
 ```shell
-docker compose exec server dz stop
+docker compose exec server1 dz stop
 ```

 If it exits cleanly, the container will also stop. Otherwise a crash is presumed and the server will restart. Ideally, the server would always exit cleanly, but... it's DayZ.

 The dz script manages what's necessary to configure and run it:

 ```shell
-docker compose exec server dz rcon

 To reset the RCON password in the Battle Eye configuration file, simply delete it, and a random one will be generated on the next server startup:

 ```shell
-docker compose run --rm server rm serverfiles/battleye/baserver_x64_active*

 To stop the server:
 ```shell
-docker compose exec server dz stop
+docker compose exec server1 dz stop

 The above sends the SIGINT signal to the server process. The server sometimes fails to stop with this signal. It may be necessary to force stop it with the SIGKILL:

 ```shell
-docker compose exec server dz force
+docker compose exec server1 dz force
 ```

 When the server exits cleanly, i.e. exit code 0, the container also stops. Otherwise, a crash is presumed, and the server will be automatically restarted.
