Update chat-commands.js

Added a box to /spin, /balance and /maxwin. If it crashes the server remove:

showOrBroadcastStart(user, cmd, room, socket, message);+    
		showOrBroadcast(user, cmd, room, socket,+      
		'<div class="infobox">' 
And 

'</div>'); from the commands modified.

I also added /hideauth because its in demand and other servers have incorperated it into there server.
