Title: convert gallery shortcode to Open Graph protocol images

Add images featured within a posts's [gallery shortcodes](http://codex.wordpress.org/Gallery_Shortcode) to Open Graph protocol images.

Images and galleries are the big feature of WordPress 3.5. Add support for gallery images as Open Graph protocol image array values.
