Small improvements to the “Show parent folder name in tab title” option

Small improvements to the “Show parent folder name in tab title” option:

• parent folder name is displayed in opened documents list;
• parent folder name is displayed in a different color from the file name.

After dark theme:

I think visually distinguishing file name from path could be useful, but it will be probably tricky to find a color which works on active/inactive tabs for both light and dark themes. (e.g the FlatLaf light screenshot is a bit hard to read for me at least)

The test output window reduces the contrast for less important stack frames for example (#6695 has screenshots).

This is how it computes the color:

netbeans/java/junit.ui/src/org/netbeans/modules/junit/ui/api/JUnitCallstackFrameNode.java

Lines 63 to 73 in 7d89336

	private static String hiddenColor() {
	// note: the tree adjusts the color automatically if the contrast is too low
	// which would have the opposite effect of what we are trying to achieve here
	float a = 0.6f;
	Color f = UIManager.getColor("Tree.foreground");
	Color b = UIManager.getColor("Tree.background");
	return String.format("#%02x%02x%02x",
	(int)(b.getRed() + a * (f.getRed() - b.getRed())),
	(int)(b.getGreen() + a * (f.getGreen() - b.getGreen())),
	(int)(b.getBlue() + a * (f.getBlue() - b.getBlue())));
	}

It does also use the colors from the actual component as input instead of using a hardcoded value.

btw If you can't access the actual tab component, this might help to figure out what the key is - if it has one:

    UIManager.getLookAndFeelDefaults().entrySet().stream()
            .filter( t -> t.getValue() instanceof Color)
            .sorted((o1, o2) -> o1.getKey().toString().compareTo(o2.getKey().toString()))
            .forEach(t -> System.out.println(t.getKey()+ ": " + t.getValue()));

@mbien thanks for the example. Made the changes and updated the screenshots.
