TCK should test bean deployment archive behaviour more thoroughly

The TCK does not currently test that the behaviour of bean deployment archives confirms to the spec. In particular we need tests for:

• Different interceptor ordering between BDA's with the same scope
• Tests that all beans in a war are visible to each other (and WEB-INF/classes should be visible to WEB-INF/lib)
• Ear /lib is visible to everyone
• Portable Extensions are loaded correctly and any beans they define are defined at a global scope (as per the current spec, this may change in 1.1)
