Support for [gallery] shortcodes with no specific IDs

[leewillis77]

Following on from #64 I wanted to provide a sample export file, and demonstration of how that should be handled. A gallery shortcode with no files will create a gallery of all attached media.

See the sample export XML:

Here's the real WordPress page that generated it showing the gallery:

Thanks @leewillis77 do you know how are images like https://www.leewillis.co.uk/wp-content/uploads/2011/08/screenshot-1.png linked to https://www.leewillis.co.uk/product-options-for-wp-e-commerce/?

I can see attachments like https://www.leewillis.co.uk/wp-content/uploads/2011/08/screenshot-1.png in your XML
I can see pages like https://www.leewillis.co.uk/product-options-for-wp-e-commerce/
However, it is not obvious to me how are they linked to each other in the WordPress XML.
I need that linkage to create a list of IDs for generating the correct gallery code in this case.

@ashishb The post_parent of the attachment is the ID of the page:

Thanks @leewillis77 for pointing that out.
