SplashScreenHelper output progress in console for text-only mode

This commit makes this changes:

- SplashScreenHelper is now local in Base constructor
- if SplashScreenHelper is instantiated with a null SplashScreen
  instance then it outputs progress in console and avoid to make
  calls to Swing toolkit
- The parsing of command line arguments is anticipated so we can
  determine if we are in command line or GUI mode early and setup
  objects that produces output to not use graphics toolkits.
- In this case the SplashScreenHelper is initialized with a real
  splashscreen only if we are in GUI mode
