This introduces a new UI element for displaying the client IP address when a search for "my ip" is used. Note that this does not show the IP address seen by Google if Whoogle is deployed remotely. It uses `request.remote_addr` to display the client IP address in the UI, not the actual address of the server (which is what Google sees in requests sent from remote Whoogle instances).
