Fix emoji functionality

[mayeaux]

Twemoji is spewing errors nonstop saying cannot read property childNodes of undefined

Needs to be fixed, makes dev really difficult. Honestly I'm not even sold on the twemoji module, the emojis look a little ugly/nonstandard, I'm pretty sure there is a better option which would be nice to be incorporated (we can use the same filter pattern though)

I agree that the current emoji don't look good. Apple's emoji have my preference.

Maybe something usefull here: https://www.npmjs.com/search?q=emoji

I just removed twemoji from the swipe page, it only errors there. Will hopefully replace this with a dif module soon
