Upgpkg: 1.9-1
Add suspending capability for the minecraft server through the control script and an additional screen session which listens on the same port with netcat. * Update .conf accordingly * IDLE_SERVER can be either true or false * The default is no idle server * Choose an available netcat flavor automatically Variable renaming in .install. Notify the user of kept directories on post_remove and alter ownership to root before removing the game user. Print error messages to stderr.
