correct tagging for semi private access

Welcome Twizy -- The routes should be drawn and tagged as pertains to their use by the general public, not those with a private arrangement with the landowner. How this is best tagged depends on the way that the payment is taken and the permission issued.

• If there's a physical barrier on the route where anyone may enter after paying a fee, tag this as barrier=toll_booth and further clarify the payment with a toll=* tag and possibly toll:*=* subtags.
• If the payment is not a toll paid for the route, but rather something like a general use fee for the area that anyone may pay (even though some special people may be allowed to visit for free), tag the route access=customers and clarify the fee with a fee=* tag and possibly fee:*=* subtags.
• If public access is generally not permitted but exceptions are made on an individual basis, tag the route access=private. You can also still add fee=* info if applicable.

Note that there's no guarantee that any particular navigation app will respect these tags -- but it's a good idea to add them anyway.
