feat(roleColorEverywhere): color blending from multiple roles

[EnergoStalin]

It was sitting in my repo long time soo let's try to get it upstream.

Hit me if some changes required.

This enable automatically blending colors from selected roles on the server.

To show highlighted roles on the server.

This will look like this

Here you can click role circle to remove from the list.

As well as just hit remove from coloring list button which is togglable so role adding is done via this button too.

This is how user looks like.

For users with no roles used in coloring list fallback to default user color.

When only one role matches blending skipped and this role color is used.

This solved problem of being forced to look at user everytime to check out their role or multiple roles.
