Shell Script - rdesktop.sh (updated)

Ok. I have made some major changes to my rdesktop.sh script. I was looking at it and said to myself 'why the crap did I do that'. ha It is much faster now as it doesn't check to see if the remote host is running remote desktop. I just let it assume that it is. It will fail and then move on faster than if a check is done to see if its running the service. I also made it a bit more interactive as you can change the username AND password for each instance you run the script. That makes it so you can run multiple username & password combos against a host (I think I may write a script to take input from a username file and a password file to make it even more dynamic).
