* Returns the postcode tidied up, and checked

* Note: HK does not use postcodes, so easy to add support for that?
*
* @param address An object that is expected to have a "postcode" field, and a
* "country" field (containing a 2-letter country code).
* If country is "ja" it expects 7 digits, and it will put a hyphen after the first 3 digits.
* (If 3 digits, it accepts that too.)
* It copes with whitespace anywhere.
* Anything else shows a blank string.
* If country is "uk", it makes it uppercase and expects [A-Z][A-Z]?[0-9]{1,2}[A-Z]?\s*[0-9][A-Z]{2}. The whitespace in the middle is always changed to be a single space.
* @todo: Actually A99A and AA99A are not allowed. I.e. if two digits then it can never be followed by another letter.
* @todo In fact [A-Z] is too liberal. see the wiki page for details.
* @todo Are we supposed to support overseas territories as part of "uk"? They allow 4 letters as
* the first part, with no digits. And Anguilla is A1-2640.
* @return The postcode tidied up. If invalid (or not given) then "" is returned.
*
* @internal Reference for UK postcodes: http://en.wikipedia.org/wiki/Postcodes_in_the_United_Kingdom
*
* @todo MOVE this to the open source library. In fact move the logic to another
* function (e.g. part of jquery validate?), and then just have this helper use that.
* The reason is that this logic overlaps with validation.
* ---> In fact, see jppostcode in html_flexdesk.js and formatAddress(), where
* we are already duplicating quite a bit of this logic!
