Daniel Quinn 090565d84c Tweak the import/export system to handle encryption choices better
Now when you export a document, the `storage_type` value is always
`unencrypted` (since that's what it is when it's exported anyway), and
the flag is set by the importing script instead, based on the existence
of a `PAPERLESS_PASSPHRASE` environment variable, indicating that
encryption is enabled.
