Purge $dont_add_double_new_line_for_block_elements and dependant code paths.
Move _new_lines_around_block_level_tags out of _get_extracted_html.
Commment broken code to retrieve the TLD based on the story_url.
This code actually had no effect so I'm removing it to simplify the code base ahead of the extractor changes.
We can consider fixing and reenabling after we decide on the extractor changes.
