Refactoring whois spice

Changes:
- Provided explicit template for whois info table rather than inheriting template from downstream code outside of this repo.
- More semantic HTML:
  - For available domains: introduced `<p>` and `<span>` tags instead of inline text nodes and `<br>` tags and removed duplicate `<strong>` tag.
  - ~~For taken domains: refactored table into a more semantic definition list for key/value pairs.~~
- Made code formatting consistent (now only follows one style for things like whitespace, quotes, etc).
- Refactored JS to use function statements rather than function expressions where possible. This has the following benefits:
  - This is the most readable way to obey the [onevar rule](http://wonko.com/post/try-to-use-one-var-statement-per-scope-in-javascript).
  - This will give a named function in a stack trace in the debugger rather than an anonymous function, which makes debugging easier.
  - There is a [small performance advantage](http://jsperf.com/fn-expression-vs-statement).
- Put double quotes on available domain names instead of single quotes.
- Added [Oxford comma](http://thumbnails-visually.netdna-ssl.com/the-oxford-comma_52c855ed979ed_w1500.jpg) to register domain links.
It might be a littler nicer for the user if these UTC dates were converted to local as well.
