Subject: Fix NEWT KeyEvent: Deliver keyChar w/ pressed and released; Deliver
 proper modified flags and modifier-key events; Simplify Windows key handling

Preface: Modifier-keys are SHIFT, CTRL, ALT and META and they have a matching modifier-bit.

- Simplify Windows key handling
  - Employ MapVirtualKey(..) for virtual-key to character and scancode to virtual-key mappings,
    allowing to drop tracking of keyCode to keyChar in java code.

    This also removes the platform restriction of delivering keyChar at TYPED only.

- Deliver keyChar w/ pressed and released
  - Due to the lift restriction on the Windows platform (see above),
    we can deliver keyChar w/ all key events on all platforms.

- Deliver proper modified flags and modifier-key events
  All modifier-keys deliver pressed, released and typed events
  with their modifier-bit set.

The above is covered by unit tests, which passed on X11, Windows and OSX (manual test run).
