Wide/flipped/reversed bttv and ffz emote support

[braintweak]

It's most likely a feature request than an issue, but: Bttw and ffz add-ons have emote modifiers, allowing any emote to become wide/flipped Y/flipped X and no space mode.

It would be great if dank chat could display those emote modifiers properly.

The list is: w!, z!, v!, h! for bttw modifiers. ffzX, ffzY, ffzW, ffzCursed for ffz modifiers.

It would be great if those were rendered properly in app.
