Subject: [PATCH 1/2] Match emojis by long name

For example, searching for `:tong` will now match `:stuck_out_tongue` because the query `:tong` has all non-word characters removed, becoming `tong` and is then matched against the (long) names of emojis such as `smiling face with open mouth and tightly-closed eyes`.
