- move the javax.enterprise support package to be a top-level module so both errai-ioc and errai-cdi can depend on it. - add support for @Specializes in errai-cdi. - cleanup the way that event qualification is handled to make it more clear and consistent. - introduce the @Default qualifier to be consistent with server-side CDI.
