Disabling JavaFX minimise/maximise/etc buttons

[Tom Schindl]

Hi,

The question for me is what we want:

* disable iconification / maxification completely (even through
  code) => then an iconifiable property is appropriate

* disable iconification / maxification through trimbar buttons
  => then I'd vote for the possibility to set the buttons enabled on
     stage through a list-property and an enum

  In code this would be:
  Stage s = new Stage();
  s.setTrimButtons(TrimButton... buttons)

IIRC in SWT one can set them individually no matter if the parent is set
or not, Steve would know better I guess.
