Develop mechanism for easy synchronisation from staging to prod

[hubertlepicki]

The usual case that we use translator is that client translates the web site on staging, and the translations are being pulled into production. I think there is a rake task and api that @dziemian007 developed somewhere, maybe on branch "rb". But I am unsure if this is correct solution.

We need something that would work with both capistrano and heroku.

The feature needs pondering about, proper design of the process and implementation and documenting of the process so other developers can use it.
