Misc OSX/SWT: OSXUtil.RunOnMainThread(..) refinement; Fix Test*NewtEventModifiers for SWT (TestNewtEventModifiersNewtCanvasSWT)

- Misc OSX/SWT: OSXUtil.RunOnMainThread(..) refinement
  - 'waitUntilDone' is implemented on Java site via lock/wait on RunnableTask to not freeze OSX main thread.

- Fix Test*NewtEventModifiers for SWT (TestNewtEventModifiersNewtCanvasSWT)
  - Deal with SWT's requirement to run the SWT event dispatch on the TK thread,
    which must be the main thread on OSX.
    We spawn off the actual test-action into another thread,
    while dispatching the events until the test-action is completed.

- AWTRobot: Add 'void requestFocus(Robot robot, Object obj, int x, int y)'
  - Use waitForIdle() only if programmed in Robot (Deadlock w/ OSX SWT)
  - Required for SWT usage (see above)
