This fixes the handling of arguments -- they are now passed to subviews, and they don't cause warnings about array_merge.
It's finally time for views_union to have an official release. People were having problems running views_union because it was based on an early, non-stable api for views 1.6. Now, it's been updated to the stable views api, and should work.
Initial release. It worked for us so far, but we're reluctant to say this is "1.0 ready" until we hear that it's working for other people.
