native cs_set_user_model(index, const model);
Sets the client's player model.
This is not a one-time set. The CStrike module will remember the selected model and try to prevent attempts at changing the player model, or immediately re-apply it if necessary.
This function has no return value.
If the client index is not within the range of 1 to MaxClients, or the client is not connected, an error will be thrown.
