Adding modifications as per conversations

A major problem with using JOptionPane this way is that you cannot provide the user with better feedback as to what the problems are with their submission.  I added code `editGame(gamesDLC)` so that it will attempt to edit the bean again, but it will basically be reset to what it was before (empty for the "add" function), so the user loses all of their work.  Using a different panel and validating data before closing the form is preferable.
