Default behaviour for Shift+Backspace

[effad]

Expected Behavior

Shift+Backspace should work exactly like Backspace without any modifier. All the other text widgets in JavaFX behave that way and a lot of text editors (kate, notepad, textareas in browsers, ...) do so as well.

Actual Behavior

Shift+Backspace does nothing.

Reproducible Demo

Use any CodeArea or other Demo, and press Shift+Backspace

Environment info:

• RichTextFX Version:0.10.2
• Operating System: Linux
• Java version: 12

Current workaround:

		InputMap<KeyEvent> allowShiftBackspace = InputMap.consume(
			keyPressed(KeyCode.BACK_SPACE, KeyCombination.SHIFT_DOWN), (e) -> textarea.deletePreviousChar()
		);
		Nodes.addInputMap(textarea, allowShiftBackspace);
