Implement #3491: Clicking the PDF icon in the linked files editor opens the file

[tobiasdiez]

Resolves #3491. A click on the PDF icon on a linked file in the entry editor opens the file. This is consistent with the behavior in the main table and thus I didn't added a new button and / or changed the double-click behavior as it was suggested in the issue.

• Change in CHANGELOG.md described
• Tests created for changes
• Screenshots added (for bigger UI changes)
• Manually tested changed features in running JabRef
• Check documentation status (Issue created for outdated help page at help.jabref.org?)
• If you changed the localization: Did you run gradle localizationUpdate?

A beautifully simple code change :)

So one click opens the PDF and a double click opens the modify file dialog. Sounds fine by me.

That's a nice solution. Btw, do you have any idea why the second file in the listvie does not indicate the blue selection ? Although it is selected

@lenhard The beauty of JavaFX!
@Siedlerchr No idea. Similarly, there are these annoying padding problems of the first row. The "beauty" of JavaFX! 😄
