Spam regulation and Kick command & fixed solution to use /externals/craft.net not ../craft.net

Spam system:
you can only send a message 4 times in a row,
counter is reset when you send a different message

Kick command
only ops can kick
when you are kicked it shows "You were kicked by [player]" ([player] being the person who kicked you)
it also prints "[player] was kicked by [player]" to the server chat.

I have also fixed compile order and project dependencies location so that it will compile if you only fork PartyCraft.
