Title: Unicode mapping, codepoint fixes, and tests!

Hot on the heels of the http://emojisaurus.com launch comes this hot pull request.

Inspired by #35, I added methods to convert name→unicode and unicode→name.

```ruby
>> Emoji.unicode_for("+1")
=> "" [redacted to pass github's PR validation]
>> Emoji.name_for("\u{1F496}")
=> "sparkling_heart"
```

I added a suite of tests, one of which attempts to verify our unicode codepoints. Here's how it looked prior to this PR.

I merged in #26 to fix all but one of those. Turns out :stars:'s codepoint was misidentified so I fixed that up too (8e098547ad56825337e7bb5472ac2f1a625ed84f).

That leaves us with one new failure because :warning:**we're missing an emoji!**:warning:

@juliamae, how did you generate the .pngs initially? We need a new one for "NIGHT WITH STARS" `U+1F303`
