Ticket status markers in channel names are now on by default

Ticket channels now show 🔴-ticket-0042 when Wallu hands the ticket to staff and 🟡-ticket-0042 once a staff member replies, without any setup. This applies to existing servers too. To turn it off, change the markers or check that it's on, go to Ticket System in settings (Wallu needs the "Manage Channels" permission) - more in the ticket automation guide.
