Emoji update

Our emoji set is a bit out of date now, having been the same for a long time whilst emoji's have moved forward.

I'm pretty sure that it's pretty easy to add more options into this type of board in the Admin CP, please can the selection be updated with a bunch of shiny new ones as you'd find on popular social media apps? eg

Laughter with tears
Hysterical laughter
ROFL face
Smirking
Drooling
Deep thought
Fire
Biceps

You know the kind of things I guess.
