Fix for #795
WP-e-Commerce javascript updates

* Check so that we don't start the process of getting the customer meta unless there are HTML elements where it would be displayed

* Check the get customer meta return structure to be sure that elements being retrieved are present before accessing them, avoid js warnings when elements not present
handle the case where get customer meta is called and the caller doesn't specify any meta keys to get.  Proper response is to return all well defined meta isntead of an error.

enumeration to be changed.
