Express Checkout 3.0 issues to validate/confirm

• The Shortcut button should be alongside both 'Begin Checkout' buttons. Ideally with 'or' between to communicate choice
• Properly align shortcut buttons.
• Can the radio button be centred against the PayPal logo (final checkout page)
• Enable Incontext and Shortcut button by default.
• Add feedback for the responses when clicking a Refund action
• I noticed after logging in on PayPal the customer gets back to a page to put in billing/ shipping info if shipping is enabled. It should be pre-populated with our response data. Also when I'm returned (with shipping items) I'm seeing something strange with shipping method
• Ensure that Message Submission ID or Token is sent with API requests.
