Emoji fallback shouldn't apply styling #157

[ajbeaven]

My use of the fallback mechanism just added is the same as was mentioned in the linked issue.

<Emoji
  set={'messenger'}
  emoji={'shrug'}
  size={24}
  fallback={(emoji) => {
    return `:${emoji.short_names[0]}:`
  }}
/>

In a case where the fallback is utilised, I'd prefer that styling wasn't applied.

Of course, feel free to close this pull request if there are other reasons that the font-size needs to be maintained!

Ah, dang, it's because the fallback is rendered inside the emoji <span>. How about this...?

I see, it does make sense. Anyone wanting to apply a font-size (or any other style) can do so by styling whatever fallback returns (i.e. it can be JSX).

I think with that version we could remove the fallback: emoji => {} defaultProps. It really is my fault, it shouldn’t have been defined to being with, but we might as well make it part of that PR.

Sure thing! I've now removed the fallback from defaultProps (do participants get notifications of commits being added to PRs?).

Sweet, thanks!

I do via email. Here’s my GitHub notifications settings and I believe these are the defaults.
