Fix in HttpCrawl (Http::crawl()) step: when a page contains a broken link, that can't be resolved and throws an Exception from the URL library, ignore the link and log a warning message.
Minor fix for merging HTTP headers when an Http step gets both, statically defined headers and headers to use from array input.
Also CS Fixer changed a lot of empty classes and constructors.
