Changes Bee Briefcase to not be suicide briefcase

- Traitors attempting to open a bee briefcase without first having
injected it with their blood, will now be stopped from doing so.
Instead, they will get a message telling them how to open it safely.
- Non-traitors can still open the briefcase as normal - resulting in at
least 5 angry bees that will surely kill them.
