bundleFileName functionality for the acr plugin

We'd have a need to rename the Java EE Application Client jar that is packaged in our EAR using the acr plugin. The canonical way to do this is perhaps along the following lines:

<acrModule>
<groupId>com.mine</groupId>
<artifactId>test</groupId>
<bundleFileName>myrenamed.jar</bundleFileName>
</acrModule>

But this is not supported. I'd be happy to contribute this change if I can receive some pointers.
