* Fix various sanity errors in plugins.
* Revert callback_type -> type transform.
* Undo paramiko_ssh 'connection' change, since this discrepancy is hardcoded in the plugin loader.
* Standardize on name and type (for callbacks).
* Fix existing author entries.
* Add 'Unknown (!UNKNOWN)' as author when author is missing.
* These are actually parsed as integers in the code.
* Revert "Add 'Unknown (!UNKNOWN)' as author when author is missing."
