This extension overrides the shipping address with the one supplied
by paypal. It is not what we want! Store the paypal address in a dedicated
field in case we will ever need it.
This commit contains enough to do an express checkout authorization (not purchase) from the cart
page, to save all relevant info, and to be able to view some of it in the admin pages. It is very
much work in progress!
Some admin features won't work (eg captures, viewing transactions), since handling of payments
and gateways needs to be generalised first. Also need to get the orders handled like those for
guest checkouts.
It's also tied to GB/UK details at the moment (this will change), and it needs a modified version
of active merchant which will be released/circulated soon.
