Remove the `CurrentUser.ip_addr` global variable and replace it with `request.remote_ip`. Before we had to track the current user's IP in a global variable so that when we edited a post for example, we could pass down the user's IP to the model and save it in the post_versions table. Now that we now longer save IPs in version tables, we don't need a global variable to get access to the current user's IP outside of controllers.
