setup.sh.txt DBARGS not implemented properly

When running a setup on a server which required hostname and port, I ran into several problems. Upon looking at setup.sg.txt (why isn't it just called setup.sh?), I noticed that the DBARGS variable has 2 issues:

1. using -z in the if statement will return true for something like "-hmyhost -P1111". Anything in quotes get a zero length return. Since DB args almost always have spaces in them, quotes are needed. After that some lines which should be using $DBARGS are not even using it, causing mysql failures.
