Add :+!: as an alternative for :+1

Problem

In many platforms (including fluxer), you can type :+1 : as an alias for the thumbsup :+1: emoji. It's a super minor issue but I personally don't like typing the :+ , then let go of shift and type 1, then press shift again to put the final : .

Proposal

It would be just a little bit easier if we could just hold shift and type :+!: to do the thumbsup emoji.
