Updated UserGuide for new license command and command line switch

Also modified the width for many of the table columns to better
show the commands with less wrapping.

This is mostly used by the developer and clutters everything up, but you may find it useful if you are trying to debug something.  I could certainly add a lot more if needed, but it's useful today.

You can load the stack with the `-l name` command line option, or from within the program by using the `load name` command.  Please note the name field is whatever you want to call the instance but avoid spaces in the name.  I'm not aware of a limit to the number of saved stacks You can have.  If the name to load does not exist, the stack will be created and saved when you exit.|
