Impersonator - Add convar to have traitors corpses show as equivalent innocent role

[NoxxFlame]

• Add ConVar to fake the revealed role
  • Have different button to switch to other mode (real or fake depending on what client setting value is)
  • Create UI to show what role they will switch to if that button is pressed
  • Possibly allow impersonators to fake the info even if they aren't promoted (if feature in Body search - Add convar to allow non-detectives to learn the team of a corpse but not the specifc role #239 is enabled)
• Add ConVar to allow non-traitor detective likes to reveal real role
