Fixed a bug in the handling of multiple charges to the same customer
Add Mercury certification tests
Mercury: use correct cert amount
Mercury: send RecordNo & Frequency tags only once
Mercury: PartialAuth on tokenized PreAuthCaptures

The action condition was only checking for 'PreAuthCapture' and not
factoring in the possible ByRecordNo suffix.

Closes #772.
Stripe: Refund full application fee if 'refund_application_fee' is set.
Merge pull request #773 from Shopify/application-fee-refund

Refund full application fee if 'refund_application_fee' is set.
Bump for release v1.35.1
Fat Zebra: More consistent handling of tokens

Switches to using the ActiveMerchant standard of passing in the token as
the payment method rather than using a Hash. The CVV can still be passed
via the options hash. The old method of passing in a Hash is deprecated.

Also cleans up the error handling to be more robust.

Closes #715.

Webmoney: Add debug mode for helper

Add mapping of debug to 'LMI_SIM_MODE'. See description on

Closes #727.
Litle: support wiredump_device

By specifying a wiredump device, such as:

  ActiveMerchant::Billing::LitleGateway.wiredump_device = File.open('/var/tmp/litle.log', 'w')

The device will now be properly passed to the LitleOnline gem for
logging.

The LitleOnline gem uses its own connection mechanism and the logging
hook will be available only in versions more recent than 8.15.

Testing Done: tested the integration with the Kill Bill Litle plugin
(see http://kill-bill.org).

Webmoney: Add #success_response to Notification

It simplifies code if we have to render something back to payment
service. We can write in our controllers code like this:

  render @notification.success_response

Closes #744.
Authorize.Net CIM: Fix extra options formatting

Closes #694.
SecureNet: Fix remote test
SecureNet: Cleanup

Removed unnecessary code and whacked some duplication.
SecureNet: Make interfaces more consistent

In particular, the #capture, #credit, and #void calls were inconsistent
with the other gateways in ActiveMerchant in that they took additional
parameters.  It's important for the gateways to share the same interface
and use the options hash for gateway specific stuff.

Now we use the authorization to hold the pieces SecureNet needs for
capture, credit, and void.
SecureNet: Deprecate #credit in favor of #refund

Closes #782.
