Masquerades Tracking Issue

[moonheart08]

This is a tracking issue for unimplemented masquerade features.
Doc is here

• Mask selection should happen before job selection, to avoid players being unable to roll antagonistic masks due to getting important jobs.
• Masquerades should have the option to reveal themselves at round-start.
• Masquerades should support vote-only masquerades, and have a way to vote them to begin with.
• Masquerade round end information should include who was initially assigned what mask, because conversion masks exist.
• Masquerades need guidebook entries containing information on what roles can be at play at various population levels.
