Add services keyword to output things into Java Console

[rzezimierz]

Hello,
title for the issue says it all :) If user has Java Console enabled, then textual representation of what your keyword is currently doing will be visible there, can be useful for troubleshooting purposes when all you have is just screenshot.

public void printToConsole(String text)
{
System.err.println("[RSL] " + text);
}
