nethack server autobuild script

so after many years of playing me some sweet nethack, i decided to put together an auto-create script that will build a working nethack server on ubuntu (testing centos && gentoo) using dgamelaunch and nh343-nao.

parts of this script were taken from all over the internet. when this script is run it will have it fully setup in roughly 5 minutes if all goes well.

script is located here
