Don't scroll output window on link click.

[mbien]

• adds another boolean to control if caret positioning should scroll (for sendCaretToPos and sendCaretToLine in AbstractOutputPane)
• calls it with false on link clicks (in OutputTab:lineClicked), overloaded method default remains true
• adds @Override to the hierarchy to be able to safely make changes. This also exposed duplicated/dead code which was removed
• luckily its all internal API

run test snippet to create some links and click on them:

public class Mavenproject2 {
    public static void main(String[] args) {
        System.out.println(Runtime.version().major()); // <- linked deprecation warning
        throw new RuntimeException("click on stack"); // <- stack trace
    }
}

Looks good, and dev build seemed to behave as desired.
