[wp-xmlrpc] Updating Custom Fields Using metaWeblog.editPost

[Burt Adsit]

It looks to me like the only way to update the custom fields in a post 
via this api is to get the post, remember the custom field ids and then 
call edit post, referring to those custom field ids again with updated 
info. Those custom field ids are unique to each post.
