[FlickrExplore] Fix and improve bridge

Browse source 
Instead of utilizing API requests for each element, the information
is now read directly from the source page, which provides information
as JSON data embedded in a script block.

The author name is returned for each element.

Improves the title and optionally adds the description if available
