Settings: fix broken signal/slot connection:

  No such slot OCC::GeneralSettings::slotForceRemoteDiscoveryOnFolders()
      (sender name:   'OCC__IgnoreListEditor')
      (receiver name: 'OCC__GeneralSettings')

The slot was in another settings page (because the button 'edit ignored files'
was moved.

Move the actual code to IgnoreListEditor where it logically belong.
Add a comment on the why this code is there.
