Add pattern to US zip code input, to trigger numeric keypad on iOS

Add pattern="\d*" to the input element for US zip codes.
This will cause iOS to show a numeric keyboard
(unfortunately doesn't seem to have any effect on Android)

Not added for any non-US postal codes as they all seem to contain
letters and/or hyphens

AVS Forcing and Removal of Server Address Check

Adding the globalcollect / adyen address and ZIP staging functions
to always force the AVS check when those fields are empty.

(Do this by unifying all the stage_(zip|address) functions.)

Additionally; allow empty address fields on the server because we
do not currently have a method of knowing when those fields are
actually required! So; we will rely on the client side check and
fall back to AVS failing when the fields are empty and we need them.
