Add IrcColors plugin

[jedenastka]

The plugin generates unique colors for usernames in chat, similar to how it works in many IRC clients.

Please add a README.md file with a screenshot

its a bit weird that this doesn't affect the member list

Looks good for the most part so this can definitely be merged once these minor things are fixed

there's actually one bug I noticed: for people who use the colour dot instead of role name (or use BetterRoleDot), the roledot has the wrong colour

also this doesn't integrate with RoleColorEverywhere which kinda sucks and should be added

In any case, I will just merge this now and we can make these fixes later

Thanks for the merge!

I think I already said this on Discord (a year ago, when I initially created the branch lol), but I don't really see value in having the role dot on while having the plugin enabled. Really, I considered patching out the dot completely, but decided against it because it's an additional patch that requires work (lazy) and it doesn't really hurt anybody (maybe someone wants to still see the role color as well, in which case they can use this combination (I don't see this being used by anyone but still)).

Agree. This is pure laziness on my part, I would probably use RoleColorEverywhere if it was integrated. Will work on this when I have time, I should probably fix #2061 first though.
