Filling the Packager gap

jpackager should work for non-modular applications as well as modular 
ones. We've tested it for simple applications with or without FX. In the 
latter case, the testing I've done has been done by first using jlink to 
create a Java runtime with the needed JDK modules + the openjfx11 
modules (using the jomds).

Andy might have additional comments.
