node doesn't show up in qconf -sh with this line added
doesn't consider master node when balancing cluster as my master is a t1.micro instance.
added some doc
added a -1 to the running nodes to remove master from teh total number of running nodes
fix if there are no available slots to add a node
added ability to update packages on cluster nodes/master
refactored to match how starcluster does things
