JavaFX project in NB should be easily customizable to meet developer requirements.

1) should be easy to use javafx tasks in the build.xml => need namespace 
AND tasks definitions loaded
2) need to add comment to build.xml explaining how to use them (may be 
also refer to "Packaging guide on javafx.com for more information")
3) need to add comment to build.xml explaining that if someone will be 
overriding -post-jar they also need to add "depends="jfx-impl" (or whatever is current target) to perform default postprocessing.
