* Use proper types reflecting assembly from the engine in 'CBitRead::Seek' (some values are 64bit, either changed by Respawn or the compiler used by Respawn). * Confirmed changes made to NETMSG_TYPE_BITS (now 511 instead of 255) and NETMSG_LENGTH_BITS (now 12 which is 511 max instead of 255). * Confirmed msg HUD types. * Enforce NET_MIN_MESSAGE on 'SVC_UserMessage::Process'. * Remove unnecessary padding and add proper symbols where padding was actually used.
