RFQ Shipping and Payment Modules

Modified from osCommerce to work with Zen Cart.

For stores that ship internationally, ship freight, special orders,or
have other variables that current shipping modules can't handle, this
is an easy fix.

Usually, if the item is overweight or is to be shipped overseas, UPS
and USPS modules won't work. This contribution is two modules in one.

1) The first RFQ allows customers to select 'Request Quote'as a
shipping method. By default, this is a $0.00 charge added to the
price (You can add a quote fee). You may then contact the customer via
email with correct shipping quotes.

2) The second module RFQ2, allows the customer to pay for the item via
normal methods, or select request for quote, pay nothing, and await
your response.

Zen Cart works as a catalog and referral, but the final shipping and
payment is done manually through your brick-n-mortar store via, phone,
fax, mail, email, etc.
