AudioTheory Piano Keys 3.0.1

Just a small patch today to address the following:

• Selecting Piano Exercises from the window nav dropdown now closes open popups/ inspectors
  
• Loaded preset name no longer shows in ear training mode
  
• Fixed a situation where the dropdowns for the scale inspector could show incorrectly
  
• Fix for B displaying as H when German note name language is selected
  
• Line style updated for ear training mode
