ip addresses: replace Google Maps with Bing Maps.

Replace the Google map on the IP address show page with a Bing map. Bing
doesn't require an API key, which makes it easier to deploy. The Google
Maps API requires to you to whitelist the IP addresses and domains you
plan to use with your API key, which is inconvenient for development
because it means maps won't display unless you whitelist your
development IPs.
