Array iteration cleanup in the actions_container.js file
Review Request #3873 - Created Feb. 12, 2012 and submitted
Some of the iterations in the actions_container.js file are using "in" operator without calling hasOwnProperty to make sure its not going up to prototype chain (http://yuiblog.com/blog/2006/09/26/for-in-intrigue/). It causes trouble when executing in some browsers like FF5. Small cleanup for actual array to just simply used for-loop with index.
Pass JS unit tests and manual test with common container and action container.
