Converted amd-container to appHandlers.

Hey guys,

Updated the example amd-container to be in sync with the standard example container. There does seem to be some strange storage bug where apps won't load randomly I reverted my code to verify and the issue I am seeing currently already existed. @brianbaker has quite a bit of experience with the AMD container so it may be best for him to investigate that logic.

Let me know if you have any questions. This should resolve "Update the container-amd example to use AppHandlers. I think its safe to only use AppHandlers for this example. We don't need two versions (like container.js and container-app-handlers.js for the non-amd example)." from #69.
