JPAContainer - invalid dependency in AddressBook demo

Hi there,

I downloaded JPAContainer v2.0.0 from the directory, and I had an issue with the demo app.

In its POM, the beanvalidation-addon dependency indicates version 0.6.3-SNAPSHOT, which doesn’t seem to be available anywhere.
I had to modify it to 1.0.0, and everything works fine.

It might be worth fixing it to ease the work of people following
the tutorial
- which is excellent btw.
