This PR will lead us towards the Promised Day, for in its wake there shall be much celebration and ecstasy as this world becomes a world suitable for developer hegemony. The first strike is thusly;
All << is converted into to_chat().
A user ahelping creates a ticket. Any further ahelps while that ticket is open will go to that ticket (and either adminhelp or pm an admin assigned to the ticket, if one has taken it).
A user can close their own ticket up until an admin takes it.
Admins can take tickets either manually or just by replying to the PM.
An admin taking a ticket notifies other admins.
If another admin attempts to take or respond to an assigned ticket, they receive a notification asking if they would like to join the ticket or cancel (any number of admins can join a ticket).
When an admin finishes with a ticket, they must close it -- both for logistics and closure for the user.
If there is an open ticket assigned to an active admin, round end is automatically delayed (unassigned tickets or tickets assigned to disconnected or afk admins do not delay). Round end will automatically continue once all active tickets are closed.
Both staff and non-staff have access to a ticket panel listing tickets, their statuses, and their messages. Non-staff can only see their own tickets. This panel is optional and all features are available inline with chat.
