Calls first subclass filters and then own methods of cleaning HTML

In the old way, in case there was an image inside a table, a problem could be generated: the image inside the table would be listed in the images array, but later removed together with the table. And we would end with more images in the array than the ranges they actually exist.

In the new way, the image is removed together with the table (and available for viewing through the "tap to see the table" link), and only after that the images tag would be searched in the HTML.
