API Proposal: RT-10376 - Add maximize property to Stage

[Radko Najman]

Hello,

this is a proposal to add 'maximized' property to Stage.

Jira: http://javafx-jira.kenai.com/browse/RT-10376
JavaFX Forum: 
https://forums.oracle.com/forums/thread.jspa?messageID=10582304

There are already 'iconified' and 'fullScreen' properties on Stage but 
'maximized' is missing. I propose to add 'maximized' property and 
corresponding methods:

public final void setMaximized(boolean value)
public final boolean isMaximixed()


Thanks,
Radko
