Setup Wizard Improvements

Getting this tool running "the first time" is greatly improved in several ways. The help files are pre-built, so, if you simply unzip and run the interface, it detected it hasn't been installed and points you to the help. The Setup Wizard was also improved to correctly create the db and tables, and permit you to create the first super user for this db. Other parts of the Setup Wizard will also check the server configuration, if the needed folders are writable, and so on.
