- Succeeded in removing the Utils.isUninstall() method.  All the logic that was being controlled by if statements using this method has been moved to the applications themselves (except for a few hacks that I've documented in the code)

- Abstracted a new WizardStep class from the Steps class which is still being used by the installer and uninstaller.  As some point we might want to separate the installer steps and uninstallers steps but I didn't do this now.
