[hpsdr] ghpsdr3 starting jmonitor

jmonitor is built using the NetBeans IDE and requires the
org/netbeans/lib/awtextra/AbsoluteLayout class.

If you build jmonitor with NetBeans then it creates a dist directory
containing the jmonitor.jar file and will also create a lib directory
with the AbsoluteLayout class in it.
