[Suggestions] Option for Roles to automatically prefix nicknames with Emojis

Sometimes you want to have more distinguishing information for roles than colours - alongside it being not great for colourblind peeps, it's also not good for screenreaders, and if you want a large number of roles to easily distinguish by sight, then colour theory says you'll struggle with getting enough variance in colours that look distinctly different.

An option that would fix this is for a role to have an Emoji associated with it, and a person's nick to have the highest level role emoji display as a prefix to their name.

E.g:

Mods on a server having a ⚔️ emoji associated with the mod role, so all mods have ⚔️ automatically prefixed to their name.

TL;dr
> Roles can optionally have an emoji associated with them
> if a person has the role, the emoji is prefixed to their nickname
> Helps with accessability, colourblindness, and large numbers of unique roles on larger servers.
