Lease fields v0.1

This script adds the shop all the fields for Lease added.
The purchase price is always 0 €, while the lease costs (seen in the shop above) calculated daily.
The lease costs are calculated from the Price field, the larger the field is, the higher the daily lease costs.
This script is compatible with all maps.
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.
