File in binary file editor is closed if file is changed elsewhere

Related to the use case for Qt Safe Renderer internal verification. Some usability issues.

If binary file is open in the editor (split view between the source code that has code for creating a certain binary file, and another view is showing the binary file contents), the binary file editor is closed and file is removed from open files list, when the contents of the binary file are changed outside the editor.

This change outside the editor is done, when the source file project is built after some changes, that yields to the updates in the contents of the binary data file.

After the file has been closed, one has to drag and drop it again from file explorer to Qt Creator to open it again to see the changes.

I think that editor behaviour is different for the external changes of the ASCII source files. 

If open file is changed outside the editor, it will ask if the user wants to reload it, and offers many options (yes, yes to all, no, no to all, no to all & diff, show details, close)
