Fixed jester roles who were changed to Innocent in Harpoon, Prop Hunt, and Come on and SLAM! keeping their role weapon

- Removed instant kill notification tooltip from the Murder knife since it didn't actually do that
- Fixed various problems with the Barrel Injustice event
-- Fixed not working for maps that use a non-standard exploding barrel model
-- Fixed not working for maps that create exploding barrels in a different way than expected
-- Fixed starting on maps that don't have exploding barrels

Changed convar saving to only saved changed values, to save space and allow easy changing of default values

Remove version number checks

Fixed loading convars from convars.json

Added manual handling of convar saving and loading to avoid problems with FCVAR_ARCHIVE. Thanks to The Stig!
- Convar values are saved and loaded from "data/randomat/convars.json"
- This means convars will no longer need to be placed in the server.cfg (or listenserver.cfg) for them to save through server restarts

- Fixed various events improperly reacting to players being moved to spectator
- Fixed various events not tracking players with duplicate names correctly
- Fixed players who respawn during various events not causing the intended effects anymore
- Fixed players who were dead when Real Gun Game started but then respawned not getting assigned a gun
- Fixed error when a player wins Real Gun Game

- Fixed realgungame ending when one team was entirely dead at the same time
- Fixed realgungame dropping weapons on the ground each time a player was killed

Removed convar archiving as it was contributing to issues joining servers
- The side effect of this is any changed convars will need to be put in server.cfg (or listenserver.cfg)

Fixed error in malfunction when a weapon is destroyed while malfunctioning
