Several minor issues (#8948)

* #8947 Plot Template : Split export dialog into file path and name
* #8946  Update multi plot title when curve is appended by copy/paste
* #8946 Separate axis object name and axis title text
* If multi plot auto name is empty, use plot title "Plot N"
* QwtPlotWidget: Double click activates Zoom All
* More testing on valid main window before use
* Return false if event is not handeled
* Improve fallback plot name
* Tree View Editor: Early exit if selected object is unchanged
Resetting selection causes flickering
* Summary Plot : Select curve object in project tree when clicking on curve
