The ugly start to knife minecraft.

**Tread Lightly**

This is the first working demo of the knife plugin. It is far from
complete, and should not be used for anything other than testing.

It will leave your server exposed with rcon on all public ip
addresses. I plan to add a firewall rule to block rcon from public
access.

At this time it only provides a command to start mcrcon over ssh.
This leaves you a interactive shell to work with for the time being.
More to come before the release.
Fixup properties... again
