Show personalised ranks in Crew Retrieval helper

[ineffyble]

The bot behold command tells you what a crew's voyage & gauntlet rank for your roster is, at the level of stars you'd have them at after taking them in the behold (e.g. 1 if new crew, current stars+1 otherwise).

If we added these ranks to the Crew Retrieval helper table, it would help people decide who to focus on.
