Disabling JavaFX minimise/maximise/etc buttons

Hi Artem, Jonathan,

I agree with what you say, except for using the initOwner() to imply 
some particular (and implicit) style that is going to be applied to the 
window. We should evaluate first whether the current implementation is 
sufficient. And no, I don't see a reason to disable maximization for a 
resizable window.

Jonathan: what is your opinion on using the setResizable(false) for the 
use cases that you outlined?

best regards,
