Subject: Fix Bug 601: Harmonize order of key events incl. auto-repeat and
 adding AUTOREPEAT_MASK modifier bit. Refine InputEvent toString(..) and list
 modifiers by name.

As now described in NEWT's KeyEvent:
+/**
+ * Key events are delivered in the following order:
+ * <ol>
+ *   <li>{@link #EVENT_KEY_PRESSED}</li>
+ *   <li>{@link #EVENT_KEY_RELEASED}</li>
+ *   <li>{@link #EVENT_KEY_TYPED}</li>
+ * </ol>
+ * In case the native platform does not
+ * deliver keyboard events in the above order or skip events,
+ * the NEWT driver will reorder and inject synthetic events if required.
+ * <p>
+ * Besides regular modifiers like {@link InputEvent##SHIFT_MASK} etc.,
+ * the {@link InputEvent#AUTOREPEAT_MASK} bit is added if repetition is detected.
+ * </p>
+ */
