Cloud api update

@parker-ldc  -- I changed `language` field to `languages` and made it multivalue.

@lisaslyis -- I replaced Aikuma/libs/aikuma-cloud-storage.jar with the latest version, and updated Aikuma code so that recording json metadata and download url get stored in the fusion table.

I still need to figure out how to obtain user id (i.e. owner id). Do you have any idea?
