More Rest test work.

Try to get the Version and Glossary tests fully working.
Implement a prototype mechanism to run DBUnit changesets on the server from a client test. (Maybe DbJUnitSeamTest will help here)
Add specific non-maven-generated components.properties file for Arquillian tests.
Having problems with default validator not being bound to JNDI.
Add Validator producer component.

This is done to decouple the validators from the components that use them. They can now be injected.
This revision also makes the raw VersionRestTest and GlossaryRestTest work under the new framework.
Still need to find a way to run DBUnit change sets less intrusively.
