Setup the project with a gradle build based on the one from the gradle-javafx plugin's sample Ensemble2.
Gradle-ise / JavaFx plugin - I fixed up a gradle build to work just as before.  I ALSO REALISED THAT JavaFx is used in jstock but it isn't a JavaFx app so I can't create deploys by using the gradle-javafx plugin.  Bummer.  I've easily abstracted jstock from Netbeans except for the Matisse Swing part.
JStock ReadMe.md update - improved the read me.
