* BUG: Fixed issue where "complete all required fields" was being shown when using Stripe. They are calling the CardType "brand" in their return object, not "type".
* Avoiding some warnings.
Added pmpro_checkout_signon_scheme filter and removed the line deleting transients when checking for notifications.
Renamed pmpro_checkout_signon_scheme to pmpro_checkout_signon_secure
GBP symbol on left.
Added ?> to getfile. Apparently, this affects some sites. (Thanks, Robert Wilkins)
Payflow seems to not like having fields urlencoded when using the API
Update frontend.css

Border color for pmpro_success message type fixed.
Stripe JS looks for a field with id AND name = CardType now so the new checkout code is compatible with older checkout templates and will avoid "complete all fields" errors.
