message from showing up

Also swaps MOTD and TM message so people actually see the MOTD instead
of 10 TM's

# Explain why it's good for the game

pt 1) if there isnt a message set for admin events, you can easily
intuit that admins arent running an event or they didnt think it was
necessary

pt 2) people werent seeing the MOTD cause it would get pushed up by 10
tm's, meaning people weren't seeing potentially important info
