Journal bundles can only be modified using "journal append"
insert rhizome bundles.
Now a new manifest can be formed, and an existing manifest modified, by giving "field=value" or "!field" command-line arguments at the end of the "rhizome add file" command (after the <bsk> argument). This makes it easier to script rhizome operations.
The "#passphrase" notation was already supported, and now the RESTful API can be used to create and update anonymous and authored bundles using only the bundle secret, just like the CLI.
