  Remove unused import in StartSliceJob
  conforming to code style
  fix typo's..
  Adjust initial view to be slightly from the side
  uses a different method to check whether a machine name excists
  Sets the languageComboBox to the default language
  Remove per-group settings for now
  Make sure to send all settings when an object overrides the profile
  Properly emit writeStarted in RemovableDriveOutputDevice
  Add xy_offset setting to list of settings that trigger a disallowed area update
  Properly trigger a reslice when the active instance is changed
  Wizardpages without hack
  Only hides the window when there are no more pages
  Only add layer data node after all processing
  Also account for "xy_offset" setting for the disallowed areas
  JSON: workaround for stutter in spiralize vase: set travel speed to printing speed
  Adds a color for the error-messages
  Shows an error message when a user tries to add a printer with a name that already excists.
  JSON: support bottom stair step height defaults changed so that the bottom distance to the model isn't violated too much
  Try to use Protobuf CPP implementation if it is available
