[code-reflection] Integrated: Fixup maven, hat.java and hat/bld.java to include arrayview example

[Gary Frost]

The arrayview (squares copy) had an incorrect pom id (copy of squares id). Which meant we had dupliicate id's

I added arrayview to hat.java (for the `java -cp hat/job.jar hat.java bld` to work 

I also removed some unnecessary deps between a few examples that really only depended on hat core.
