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.
