// SUPER HACK TO FIX DEMOS.  For a couple days, we accidently renamed 
// CTFWeaponBuilder to C_TFWeaponBuilder on the server.  This was fine for
// playing the game but broke all previously recorded demos.  Fixing this and
// re-renaming the class back to the original name fixed all demos recorded
// with the brokenly-renamed class.  To handle these demos that think the class
// is called C_TFWeaponBuilder on the server, we're creating a new class that derives from
// the real C_TFWeaponBuilder and does nothing special except that it calls
// IMPLEMENT_CLIENTCLASS and maps itself to serverclass "C_TFWeaponBuilder"
// (which, if you've followed along, doesn't exist anymore).
//
// As a history lesson, this broke from the change in tf_player_shared.h in cl 1722245
