return array ref of objects from _make_request() if a list is returned,
rather than trying to instantiate non-existent Net::Stripe::List class:
fixes test #20
Clean up test output by hiding expected warnings
"fee" was removed from the returned Charge object by Stripe,
see 2013-12-03 changes at https://stripe.com/docs/upgrades
Hide expected warnings; Fix invalid currency test.
Customer has a "default_card" not an "active_card", and this
"default_card" is a card id, not a Stripe Card object. Test 94 now passes.
Another test needing Customer->active_card changed to Customer->default_card
Correct Test: if cancelled with "at_period_end", a subscription will
not yet have "ended_at" set. Test 114 passes now.
Yet another test needing Customer->active_card changed to Customer->default_card
test for 1, not "true"; swallow an exected warning to /dev/null...
All existing tests now pass!
Add ability to add "metadata" hashref to Customer object creation.
Multiple subscriptions are now possible, updating is different
from creating, there is a list subscription method
