/*

  EXT_CSQC is the 'root' extension
  EXT_CSQC_1 are a collection of additional features to cover omissions in the original spec


  note the CHEAT_PARANOID define disables certain EXT_CSQC_1 features,
  in an attempt to prevent the player from finding out where he/she is, thus preventing aimbots.
  This is specifically targetted towards deathmatch mods where each player is a single player.
  In reality, this paranoia provides nothing which could not be done with a cheat proxy.
  Seeing as the client ensures hashes match in the first place, this paranoia gives nothing in the long run.
  Unfortunatly EXT_CSQC was designed around this paranoia.
