Custom color modifiers and mutant modifiers (paw, claw) are added too.
Additionally, a feature to generate diverse emojis are added. To use it, put the emoji you want, then write :skin-tone-, pick a skin tone, and remove the space between them (`:ok_hand::skin-tone-2:` etc). When you post that, it'll be sent as a diverse version of that emoji.
