Set MPOwner owner v0.1

This script makes it possible for all taxable vehicles specify an owner. By default, each vehicle has the owner "no", which means that each player can use the vehicle.
Use the key combination [right] Shift + R, the owner between "no" and themselves be replaced. Is the vehicle a player can only use the vehicle that player, all other players can not enter.
If a player tries to enter a vehicle that is not his, he gets a warning.
When switching through the vehicles with tab (whether forward or back) are all the skipped not a self or "no" part.

Changing the owner only works if all things are uncoupled, but the owner is always displayed.

This is the first version of this script, which I did not want to deprive you.
I I'd appreciate constructive criticism or change requests.
