SatNavVoicePackCreator_v1.0.3

Last edit, which added the How to tab, glued the line # --- helpers onto def set_status(...). That commented out set_status, so creating a pack crashed with 'App' object has no attribute 'set_status'. It would also have broken every other action that reports a status, including Build, Install, Save and Import.

Fix: Method back was put its own line.
