The Revolutionaries Rework (#309)

The one rework to rule them all.

Revolutionaries as a gamemode is currently fairly derided as a gamemode
that relies too much on murderboning and being too "metagamey" to
counterplay. This design document aims to remake the Revolutionary antag
into one that escalates appropriately in presence throughout the round,
has clear end conditions and doesn't encourage round removal.

> "I want to see people kidnap the QM, lock him in a room with a bunch
of communism posters and have 5 medical doctors wearing red headbands
scream at him until he converts to the revolutionary cause"

Enjoy!

_I want to highlight the previously submitted Revolutionaries reworks
#251 and #146, as some concepts from those documents have made it into
this proposal where appropriate._
