Support xip.io wildcard DNS as a VHOST

Browse Source 
http://xip.io

xip.io is a service by Basecamp that provides a wildcard DNS service on the public internet. Any <ip address>.xip.io will return a DNS response for the IP address, same with <subdomain>.<ip address>.xip.io.

The domains plugin in dokku uses a regex to match IP4 and IP6 addresses in the VHOST file, and disables VHOST support if found. This PR changes those patterns to require that the VHOST entry **ends with** the IP address.

This is a gist where my VHOST setting is "127.0.0.1.xip.io" that demonstrates the original output, linked directly to the line from `plugins/domains/commands`: https://gist.github.com/anonymous/c529177f20b36beda80d#file-debug-log-L1373
