Whois Spice - Updates



**Updates Summary:**
+ Fixed timestamp issue.
  + The IA appears to have been displaying an ISO timestamp as it looks like the API was updated to include the timezone (e.g PST) meaning the `replace` function that was used no longer worked. 
+ Display domain NS hosts.
  + This is a useful function to have IMO. It doesn't add to much more data to the Spice (height wise)

Wondering if we should pass in an object to `data` the defines the names and URL's for these domain buying sites. Then we could easily add to the list and de-duplicate some of the HTML in our template.
