This is imprecise in the sense that a valid request *might* not be caught
if the user's class hasn't been looked up yet. But it's a tradeoff between
that and the bot having to look up every user showing any channel activity.
On Libera.Chat this is a non-issue *if* the user joins the channel after the
bot does, as account names are broadcast upon joining. Additionally, the act of
logging in is also broadcast (with a ACCONUT event).
Parses a message to see if the message contains one or more URLs. Merely passes the event on to onMessageImpl.
This function is annotated with Permissions.ignore, but we don't mix in MinimalAuthentication. Ideally we would annotate it Permissions.anyone, but then *any* channel message would incur a user lookup, which is a bit much.

Revisit this if it proves to be a problem.
