For the record, this comes from #571 (my bad...).

Another simple fix for another simple bug, thanks @YaManicKill! :-)

@JocelynDelalande, @erming, @floogulinc for a second review?

I believe there are some styles that rely on button selector, did you look at these? Ideally they should be changed to .user

[astorije]

Good point! @YaManicKill, could you take another look?

[AlMcKinlay]

Ah yes, sorry. I didn't notice that the colours weren't working. It was always showing colours for nicknames. I've fixed that now. Everything in #chat that was using a button is now also using .user. Should be good now.

[xPaw]

By the way, user.tpl uses <button> for users too, should be changed?

[AlMcKinlay]

Well, I think it's unlikely people are going to copy the list of users, but I'm happy to change that as well, if people want. Need to rebase now anyway, thanks to @erming merging so much today :-P

[AlMcKinlay]

I think this should be good now, assuming that no one thinks there's a need to ensure the user list is copy-able.

[JocelynDelalande]

reviewed and tested, that's a 👍 for me.
