Revised file processing screens on the backside of miniLock

Here is an implementation of the human interface design mentioned in issue #42.

And 3 videos that show it off:

Save a secret song for my parents

Why have you decided to replace the term "recipients", which is well-defined throughout the design documentation, code, and user interface, with "audience"? Please don't make up terms and stick to the ones defined in the design documents.
