8u20 review request: RT-35443 Provide a headless glass implementation integrated with our JUnit tests

[Daniel Blaukopf]

Hi Steve and Anthony,

Would you review the following change to our build/test scripts to allow running JUnit tests in headless Monocle on desktop platforms?

https://javafx-jira.kenai.com/browse/RT-35443
http://cr.openjdk.java.net/~dblaukop/webrev-20140121-1743-RT-35443/webrev/

Currently all tests run with this patch pass.

Thanks,
Daniel
