@brief Convenience tab bar implementation
This tab bar differs in several ways form the QTabBar:
- you can close a tab by double-clicking it or through its context menu.
- it works based on tab identifiers (a fixed id stored in tab data) rather than on tab indices, which might
change when inserting or removing a tab.
- it accepts all drag-and-drop actions and emits signals to handle them.
