WEBrick long request fix

Sometimes when running ScoutRealtime behind a firewall, the requests might take ~5s each. This causes some delays in the realtime monitoring.

vim /home/alf/.rvm/rubies/ruby-1.9.3-p545/lib/ruby/1.9.1/webrick/config.rb

Update :DoNotReverseLookup => nil, to :DoNotReverseLookup => true,

scout_realtime stop
scout_realtime start

Setting SuperUser on a virtual server

sudo /usr/sbin/murmurd -ini /etc/mumble-server.ini -supw [password] [id]

This will create a SuperUser password for the virtual server ID. If none is given, 1 will be used.

This also sets the password without having to restart the server.
