Multiple additional arguments not working

Hi @joedwards32 ,

in `entry.sh` the CS2_ADDITIONAL_ARGS env var is used with quotes:

```
"${CS2_PW_ARGS}" \
        +sv_lan "${CS2_LAN}" \
        +tv_port "${TV_PORT}" \
        "${CS2_ADDITIONAL_ARGS}"
```

This seems to break when trying to use multiple arguments. More details in the PR:

Best regards,
Pascal
