  Terminal strip item can saved / loaded to .qet file
  See previous commit...
  Move terminal strip drawer class in is own file
  Fix wrong use of QStringLiteral and QLatin1String
  Double click a TerminalStripItem open the editor
  Minor change about checkable QAction of QetDiagramEditor
  Minor : corrects a minor aesthetic defect when unbridge terminals
  Revamp code
  Add and move terminal strip item are now managed by undo command
