Bug 1188, Bug 1186: NEWT Window: Support non-resizable, minimize, maximize, alwaysOnBottom and sticky/all-desktop (Part 1)

Change also implements Bug 1186: 'NEWT Window: Use a Bitfield holding all state flags and expose it accordingly',
since it is essential for an efficient implementation.

Part 1:

- Bug 1186
  - Using Bitfield, holding public (Window) and private state bits/mask

- Bug 1188
  - Window adds:
       - [is|set]AlwaysOnBottom(..),
       - [is|set]Resizable(..),
       - [is|set]Sticky(..),
       - [is|set]Maximized(..),
       - isChildWindow(),

  - Full implementation for X11

  - TODO: Implement for OSX and Windows

- Manual tests:
  - TestGearsES2NEWT, TestGearsES2NEWTSimple and TestGearsES2NewtCanvasAWT
    utilize new NewtDemoListener, which has a key-listener to perform
    all [new] actions. See source code of NewtDemoListener.
