Improve ArtemisResourceAdapterFactory

[zhfeng]

one thing I added in my implementation, is a way to wrap the message listener in a custom class. in my situation I just hardcoded the common behavior: reading some common headers and adding them to a custom request context.
there was also a question on support for duplicated context. right now I am storing this request context in a request scope bean for jms messages, and into the duplicated context for everything else.
