Add check for hosts that are guests

[ChanceM]

Adds check for guest records that were clobbered by being a host and adds a guest file output.

Fixes JupiterBroadcasting/jupiterbroadcasting.com#376

@elreydetoda wanna have a look at this one too? Low-ish priority.

Ya, I can try and take a look at it this weekend.

The scraper is currently a lot more difficult to validate consistency, and I want to make sure I don't break anything with plenty of time to validate changes.

This is the way.

@elreydetoda I noticed there is a bash script in the repo that links all hosts to guests... seems a small assumption, but probably safe. I still think the cascade method might be something to look at since it does look like JB is accepting PRs against the people content for future updates not populated by the scrapper.

It might be a messy rebuild but would set it up for easier updates to both profiles while also being flexible enough to allow changes to just one if needed.
