Update Antagonist/Bribery rules

[Colin-Tel]

About the PR

This PR contains rule alterations as suggested in the previous community meeting.

Why / Balance

The antag rules will likely benefit from the addition of the header that declares, in summary, "just because you're an antag doesn't mean you can't stop roleplaying."
The bribery line was added because some less-important things should be able to be bribed for a good enough reason, while it previously was unclear if such a thing would constitute as a rule break.
