Update zanata public package script to new JBoss AS 7 config.

Change the public package scripts and overridden files for the zanata standalone public package.

This works with both EAP 6.1 (Alpha+) or JBoss AS 7 (tested with 7.2.0). 
It does not do any hibernate library replacement. That needs to happen before the script is ran.

In the future we might look at using augeas to modify the files in the Jboss distribution. specially ones with smaller changes like `module.xml`
Also, more research can be done on how to strip unnecessary AS 7 components to reduce the size of the package.
