Allow the server to ignore files or groups of files at deployment time

Legacy and migrated applications may occasionally contain files which are incompatible with the Java EE specification and can cause the application to fail the deployment. The difference between those cases and really faulty Java EE applications lies in the intent of the developer - whether they wish for those files to be picked up by the server and processed, or not.

In such cases, it may be useful to expand the deployment specification and to be able to instruct the server to ignore particular files at deployment time.
