Allow displaying role colors separately from the name, or hiding them

Problem

Not all role colors are universally readable on all backgrounds. #1363 may be one way to resolve this issue, but the customizability of the Fluxer clients may make it more complex than it needs to be. This can also be used for accessibility purposes.

Proposal

A setting should be added under "Accessibility" that allows users to have names displayed with a role color (the default option), have a colored dot next to the name, or hide the role color from chats and member lists altogether. When the colored dot option is chosen, the color of the topmost colored role is displayed, and its name is displayed on hover. If the user has no colored roles, the dot does not appear.

Notes

This feature exists on Discord, in accessibility settings. obraz When hovering on a colored dot, the role's name appears. obraz obraz
