whitespace between emojis

[cod3licious]

Thanks for this great library! :)

To facilitate tokenisation it would be great if additional whitespace could be added before and after each emoji.

[jfilter]

I'm not sure if this can be easily done. There are emojis that consist of several sub-emojis. And I don't want to go into the direction of writing an emoji tokenizer just to add whitespace.

If people need some very special emoji handling, this other package may help: https://github.com/carpedm20/emoji

(If somebody comes up with an easy way to accomplish: I'm open to pull requests.)
