Introduce a way to exclude classes or packages from scanning

Better support for dual SE and EE applications. I have some weld-using jar's that can be deployed on a Java EE and work standalone. It is possible to get this to work using both weld SE and weld EE but it is a pain. F.x. when deployed under glassfish weld will fail unless I include a few weld SE dummy classes.... Weld should either combine weld SE and weld EE OR there should at least be some support for having weld ignoring some of my classes/packages depending on which environment it is running under.
