NEWT/JOGL: MacOSX Update

Feature related:

- Added always-on-top

- Added translucency

- Child Window Position

  - AWT parent: manual traverse up the tree and calc position on screen
    (Problem: the parent view rect is not at the proper position,
     but covers the whole frame)

EDTUtil related:

- Works now w/ AWT ot headless (again)

- OSX native JNI callbacks gathering JNIEnv properly
  and attaches/detaches thread.

- AWT case: using AWT-Event which properly dispatches our cocoa events

- MainThread (headless) case: Fork off thread w/ main class
  and kick off NSApp run().
  This leads to same behavior as w/ AWT case.

- Using DefaultEDTUtil

- Cleanup MainThread (implements EDTUtil)
  - Currently not used as EDTUtil (osx), just as launcher
  - Removed EDTUtil impl code, reuse DefaultEDTUtil

- Cleanup AWTEDTUtil (implements EDTUtil)
  - Currently not used as EDTUtil (osx)
