allow site admins to send popup messages vs just saying things in the chat.  many times i don't have the chat even open.

when site is going down.  send popup message (ex site reboot in 15 minutes).  block new players from sitting at cash tables with message (ex awaiting site reboot) until server is restarted.  this way current players should have received the message and if someone shows up inbetween they won't get caught playing during restart.
