Paint user colours in system messages

[jupjohn]

Being able to display username colours in system messages (for things like bans, automod actions, etc.) would be nice from a UX perspective as users would be able to visually parse out username information from actions quicker.

As part of this, I'd like to suggest a setting (MOAR SETTINGS) to allow for toggling between coloured and plain username rendering as some users may not want this.

Based on Neri's comment in the c7 repository: SevenTV#111 (comment)

As for the suggestion as a whole: Yeah, it's just a matter of finding places where we don't color usernames & make them colored (and clickable). This will be done by replacing TextElement with usernames with the MentionElement.

The Color @usernames setting controls coloring of usernames both in system messages and in normal messages, I'm not sure I want to add a new setting that now controls colorizing of usernames in system messages.

That sounds like an even better solution; agreed that adding another setting is silly if it's already covered under an existing one 👍
