If a HUD Message is being overwritten by another HUD Message, the new Message
undertakes the remaining Data from the old Message. Example:
HUD Message: "Headshot!" Has a holdtime of 5 Seconds.
3 Seconds later...
HUD Message: "Doublekill!" Has a holdtime of 5 Seconds, but:
its holdtime will be 2 Seconds, because, as just said, it undertakes
the holdtime and some other Stuff from the previous Message.
