Bump dependencies to lang-js 1.1.0-SNAPSHOT and rhino 2.2.0-SNAPSHOT.

Once, lang-js-1.1.0 has been released and published to maven central, the SNAPSHOT dependency should be removed, and lang-rhino 2.2.0 can be released. The lang-dynjs module was already updated with these changes, so it too can lose the SNAPSHOT dependency and lang-dynjs 1.1.0 can be released.
