feat: console help, examples and named loggers (SummerCMS v0.4.0)

Every command gets long help and examples, descriptions in imperative
sentence case, and a warn-only TestCommandsDocumented over bonfire.CheckDocs.
The plugin logs through a diary component logger instead of the process
default logger. Requires SummerCMS v0.4.0; command names and flags unchanged.

user:token:create and user:token:list gain --json, user:backfill-handles a
progress bar; planning IDs leave the descriptions.
