Subject: [PATCH] [emoji-filter] Override emoji_image_tag

This is nicer because I want to use everything that EmojiFilter
does *except* the image tag generation.

The prior implementation had to get involved with finding emojis and
gsubbing them out.

This possible now because of @kbrock's change over here:
