Move some unsafe facts that were in `safe.txt` to `unsafe.txt`

I believe this release fixed the encoding errors on Windows encountered in 7. If not, I will fix the issue in subsequent releases.

v0.7.0 added more facts, and v0.7.1 was linting and the deprecation of camelCase names in favor of snake_case names.

`getFact` -> `get_fact`
`allFacts` -> `all_facts`
`safeFacts` -> `safe_facts`
`unsafeFacts` -> `unsafe_facts`

The old method names are still available, but are deprecated and will be removed in a future release
