"Loading" dialog opens due to QT 5.5 bug

  I'm using Ubuntu 16.04, QT 5.5.1. Both Musescore and Polyphone open a "Loading..." dialog for no reason shortly after application startup.
  
  I found the Musescore bug entry, which listed a workaround commit. https://github.com/musescore/MuseScore/c…1981c5dc530d349ffd14 
  
  Reading the comments of QTBUG-47042, each QProgressDialog object will automatically display after being constructed (https://bugreports.qt.io/browse/QTBUG-47…panel#comment-301657 ). It was intended to be created and destroyed once per operation. You need to either create it during operations, or call ->reset() after creating.
  
  Interestingly enough, loading/saving big soundfonts on Windows 1.7 take a long time, but don't produce a dialog...

  Thank you for the link => the problem of the progress dialog will be fixed in the next version.
  It will also be displayed for the opening of a soundfont.
