#184 Support for scoped ear deployments added

[Scott M Stark]

Preliminary support has been added for scoped class
loading
repositories based on ear deployments. Such an ear
creates
its own class loader repository that looks first to
the deployment
units included in the ear before delegating to the
default
class loader repository. To enable an ear specific
loader
repository create a META-INF/jboss-app.xml descriptor
with:
<jboss-app>
<loader-
repository>some.dot.com:loader=webtest.ear</loader-
repository>
</jboss-app>

where the value of the loader-repository element is
the JMX ObjectName
to assign to the repository created for the ear. This
must be unique
and be a valid JMX ObjectName.
