Move jboss interceptors into Weld

(12:36:44 PM) stuartdouglas: jharting: you could actually do that for the 2.0 branch already
(12:37:20 PM) stuartdouglas: it should be pretty easy just to move the code out of jboss interceptors and into weld trunk
(12:40:01 PM) stuartdouglas: Its not high priority, and I would talk to Marius first
