Bug fixes relating to svea-15
SVEA-16, SVEA-17: Toggle readonly on elements, Saving/restoring values

'readonly' are now toggled on the readonly elements. The address values
are restored when moving from svea to non-svea combinations as good as
possible.
SVEA-18: Handle payment-specific and general form data

Handle both when a single address box is used and when one
address-box/payment method is used.

When on address-box is used for all methods the additional data will
be under the key 'svea_info', if not it will be under the payment
methods code.
