[Extension] C4: Chilhelm's Chase & Combat Collection

[Mike Serfass]

Thanks for the fix and tweak, chillhelm.
There's another error, however.
The deprecated User.isHost() and User.isLocal() functions are now throwing errors in main.lua.
They were changed to session properties.
Session.IsHost
Session.IsLocal

Also, FastTests has the same error.

Thanks!
