Enable triggering offline parsing explicitely

[koppor]

New online/offline distinction more visible in the UI:

Library menu:

Button on toolbar still asks for permission:

If "Do not ask again" (and Yes)

Additionally:

• Refactor actions to inheritance instead of if-statements in a class
  • Depends on Add support for inheritance of dialogs afterburner.fx#17
• Solved "fun" with inheritance and FXML
• Use %0 and offline/offline parameterization
• Rename "GROBID" to "Grobid"

Feature: clipboard contents now contained automatically:

(You also see here "online" and "offline" indication at the dialog title)

---

Feature itself is described at https://docs.jabref.org/collect/newentryfromplaintext.

Mandatory checks

I needed mavenLocal() to be able to load the patched version org.jabref:afterburner.fx:2.0.0-SNAPSHOT.

Not required any more.

bad architectural changes

Just for reference: Code with inheritance side-by-side:

I will now try to use composition. Let's see, how it will work out.

[koppor]

Rewritten, now we have an if/else in BibtexExtractorViewModel:

    public void startParsing() {
        if (onlineMode) {
            startParsingOnline();
        } else {
            startParsingOffline();
        }
    }

This is OK for me.

I need to have this code here, because otherwise, I get

Caused by: java.lang.NullPointerException: Cannot invoke "javafx.scene.control.Button.setTooltip(javafx.scene.control.Tooltip)" because "buttonParse" is null

[Siedlerchr]

why controller?

[koppor]

Oh, I thought, I could not it get to work without this... Strange. Removed.
