+use recipient in encryption to lookup public key in the vault, if id not given

+change encrypted file format to the one of pbp, following it:
+   - support multiple recipients
+   - encrypt 32k blockwise using crypto_secretbox() using
+     a random key, encrypt that key for each recipient with

+stores the full stuff, so I shall do it as well).
