Replace :D with 😄 instead of 😃

[MightyCreak]

Riot.im uses emojione and the auto-replacement of ascii strings to emoji (i.e. :) becoming 🙂).

I think :D should not be converted to 😃 (:smiley:) but rather to 😄 (:smile:).
In all the apps I use (e.g. Riot, Github and Slack), 😃 looks more like a "surprise" than a "it's funny".

And, actually, Slack uses :smile: for :D.
And it also seems more logical to replace :D with :smile:, since :) is replaced by :slight_smile: (no y in the end).

I've tried to change the code in order to propose a PR, but I'm unsure which file I should really change... Is it emoji.js?
