jira/client: Extend VersionService and fix Issue

Added Create and Delete for VersionService.

Removed StatusCategory part from the Issue resource struct, it is not good for
anything and there was a problem with unmarshalling, so that is solved.

review post: Make the output more consistent

Review the review post subcommand and make the output a bit more consistent with
other commands. Also dropped a few funky sentences from the output, it is more
irritating than helping to see the important info. Sorry, I am boring, I know.
