Support modding actions (time-out, ban, delete) on messages if the logged in user is a mod

[Glodenox]

With the addition of the chatbox, we now get access to more features as the user can be logged in. It is quite easy to detect when a logged in user is a mod for the channel and to support moderation actions. These could be 3 simple buttons that appear when you hover over a chat line. I highly doubt it'll be possible to implement everything the other moderation tools provide, though. User notes and such are probably going to remain out of scope.
