Called when an NWVar is changed.
Currently this hook only works for the NW2Var system (accessed by adding a 2 in between NW and Var for most NWVar functions), which will replace the original one at some point in the future
This hook is fired before the client value is actually changed. Calling the GetNW function for the specified variable name within this hook will return the old value, not the current/updated one.
Example usage of the hook. Prints out all NWVar changes.
hook.Add("EntityNetworkedVarChanged","printchange", print ) -- Trigger a change! Entity(1):SetNWString( "UserGroup", "owner" )
