Button(graphic) constructor addition breaks existing code

[Richard Bair]

The new constructor I added in http://javafx-jira.kenai.com/browse/RT-16206 breaks existing code, as we can see below reported by Hudson. As such I'm going to back that change out and close the issue as will not fix (it isn't worth breaking existing code for this minor addition).
