/**
 * An appender that writes each message to a native alert().
 * <p>
 * This class does not depend on qooxdoo widgets, so it also works when there
 * are problems with widgets or when the widgets are not yet initialized.
 * <p>
 * It allows to go through the log messages step-by-step, since the alert
 * window temporarily halts the regular program execution. That way even
 * the dispose process can easily be debugged.
